Headlines: Comments here have longer sentences, lengthier words and the better ones are properly punctuated. The best of all are very long.

There's no information about comment length in the Infodump, unfortunately. Although I wonder if this is something that could be added? I agree with not having the actual comment text in there, but it seems like comment length would be pretty harmless.

His conclusion, "Given this data, my recommendation is to not restrict comment length, or to restrict it at a high level", doesn't make a lot of sense to me. His data show that long comments are good for MetaFilter, but they also show that length is largely irrelevant to YouTube. Presumably 5000-character YouTube comments would be as inane as 20-character comments.

The Treaty of Westhphalia is not deleted for its length, but for its radical content, which cannot be unleashed on an unprepared audience. Oh, sure, superficially it seems a rather mundane document detailing the truce at the end of the Thirty Years War, but buried in it, encoded into the independence of Bremen section, is the key to unlocking the pathway to the Elder Gods and the eldrich horror therein, the breaching of which had bene the longterm goal of the House of Habsburg, and the supression of which was the true cause of the war. I risk so much just by telling you this; even now, the watchers scratch at my window, and a strange music plays just on the edge of my perception, written in no human scale and expressing an intelligence no human has ever possessed.

I think le morte de bea arthur's point was that the data shows that once YouTube comments get beyond 10 or so characters, there is little or no improvement in their ratings, whereas MetaFilter comments show an upward trend well before hitting YouTube's limit.

Personally I think the claim that removing the 500 character limit on YouTube or similar comments would directly improve comment quality is dubious. Long and well-written comments are more of a side effect of having meaningful discussions than a fundamental result of having the ability to post long comments. There are many other factors, such as the userbase, moderation, and presentation of the comments (i.e. not reverse-chronological order with only a few per page) that probably keep comments at a poor level of quality on some sites regardless of technical length limits.
posted by burnmp3s at 11:19 AM on September 29, 2009

A lot of my comments are very long, but they are also atrociously punctuated. It is actually very embarassing. The following are to blame:

(a) society,
(b) the small font,
(c) the excessive width of the comment box, and
(d) the cramped line spacing in the comment box.

If anyone can suggest a way to improve any of these items, particularly (a), I shall incorporate it directly into my comment workflow. You could then be assured that even my most logorrheal comments would include grammatical apostrophes rather than catastrophes.

I agree, he's identifying correlation where causation isn't determinable. For example there are community norms, volume of traffic, and topic ranges that also dictate commenter behavior.

But what I get out of it is that putting a low character limit on comments is not a useful means of controlling comment quality. Projecting from that, community norms, at least, are modulated by the participants, and if the participants can't write at length when the subject demands it, they're going to give up trying.

I don't make that claim. That's why I specifically say that my recommendation only applies to sites which don't have a malevolent audience. Having said that, YouTube's comments also show a slight correlation between comment length and quality.

True, and I don't claim that there is causation. The basic question I was trying to answer is whether it makes sense to restrict comment length, and the data seems to suggest that it doesn't. That's pretty much all I'm claiming.

The data shows a slight correlation between length and quality even on YouTube. However, I do point out that my recommendation only applies if you expect to have a reasonably positive community of commenters. I agree that removing the length restriction on YouTube would probably not result in more coherent comments, but merely in longer incoherent comments.

I don't really see how the data backs that up though, other than that MetaFilter comments that would be over the limit on other sites are rated highly. From the conclusion:

Since longer comments on average were rated higher, restricting comment length may cut off the best comments, or force comment writers to redact their comments until they fit – and it’s pretty hard to trim a 2000-character-text into 500 characters without removing substance.

I actually think this is probably true, but since the study did not test for this it's not really proven by the actual data. It's possible that limiting the maximum length of each entry would result in tighter writing, or more engagement due to the threads being easier to read, or some other positive effect that would make the overall comment quality better. This particular dataset does not cover cases where the comment quality is high enough to take advantage of longer comment lengths but where technical length limitations exist, so any conclusions about the worth of such limits or recommended limits is conjecture.

Also, I think the method of rating these comments by displaying them completely out of context of the thread/video heavily favors longer comments (rather than being a "slight disadvantage" as presented in the post), so I'm not sure if the data that was collected is a true measure of comment quality.

This is true, the data doesn't prove anything, and I don't claim it does. But I do think it suggests that restricting comment length is misguided. The data isn't proof for anything, but I think it is an indication of what's going on.

"It's possible that limiting the maximum length of each entry would result in tighter writing, or more engagement due to the threads being easier to read, or some other positive effect that would make the overall comment quality better."

Yes, this is possible. I can't think of any examples of websites that seem to exhibit this effect, but it's possible. Any ideas how this could be tested?

Yeah, I think I was actually being more critical of this because it gives the impression of "I have this opinion about technical comment length limitations, and here is the proof" when the graphs and data that collected aren't much more compelling than just showing some really great 1000+ character comments and making the argument that they wouldn't be possible with a limit. Of course having at least some data to objectively show that long comments can be some of the best comments on certain sites is better than nothing, but when I see graphs and statistics used to back up a claim I have a tendency to look at the data skeptically, even if I think the claim is true.

Any ideas how this could be tested?

Not easily. The best opportunity for studying the effect of the limitations would be to look at a site before and after restrictions were imposed/lifted.

I'm not sure how to account for the lack of context. Any ideas?

I rated a few of the comments when this was posted to MetaTalk before, but I gave up because it was too hard to figure out what the comments were even talking about, let alone rate them. Presenting the user with the post/video and the properly formatted comment would go a long way towards recreating the context. A lot of comments on both MetaFilter and YouTube would make no sense at all without at least knowing what the topic is. Really though, it's very difficult to make any kind of qualification about comments without reading the whole thread, or at least the parts of the thread that are relevant to any given comment. Showing some of the comments around the comment being rated would probably be a good start. It would also be easier to do on sites where the comments are threaded.

"Presenting the user with the post/video and the properly formatted comment would go a long way towards recreating the context. (…) Showing some of the comments around the comment being rated would probably be a good start."

Yes, giving the original post or video the comment relates to, or surrounding comments, is a good idea and should be possible. And yes, I definitely screwed up when I removed the HTML from the comments. I didn't want MeFi comments to look differently from YouTube comments, but in hindsight, that was a pretty dumb decision.

"Really though, it's very difficult to make any kind of qualification about comments without reading the whole thread, or at least the parts of the thread that are relevant to any given comment."

So it would make sense to reuse ratings made in the context of the comment on the site the comment originally appeared on. Perhaps using a Slashdot-like site would work, where people already rate comments. That's definitely feasible.

That way, one could also objectively test whether changing comment restriction changes average comment ratings. That would be a pretty huge project for a pretty small result, though.

Specifically, how would you improve this experiment?

People already take for granted as common knowledge that YouTube comments are of worse subjective quality than comments from practically any other online forum, including Metafilter. You do not appear to take into account this "background" knowledge people bring to the table when they participate in your experiment.

More specifically, comments that are written as if they were posted on YouTube would, I expect, get voted with a lower quality score, regardless of their length. I would imagine that, for example, comparing:

"Neo ain't got shit on this guy :p"

with an information-less comment like:

"Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."

I'll bet that the first style of comment would still get a lower aggregate score.

That's just one source of a priori bias on the part of voters that I think would need to be tested as an effect (using random or Markov-generated comments, for example, as controls) before you could begin to evaluate comment length as a significant effect.

There are other effects. Metafilter comments originate with a very specific demographic of commenters, who are, all else the same, probably older and more educated, and who, as a result, are likely more comfortable with expressing complex ideas without regard for length within the flow of a larger conversation.

When a short comment is pulled at random — and what is defined as random comment sampling? — does its length ignore its potentially critical, i.e. "high quality" contribution to a larger thread of discussion? It would seem hard to evaluate this effect without having voters evaluate whole threads.

Independent of length, comments may not be hermetic, gut-level expressions of a single thought, the way they are, on the whole, on YouTube. The "big picture" nature of how site members contribute within a thread can be a more intangible and difficult effect to suss out.

When the commenters come to the sites to contribute, do the educational or other experiential backgrounds result in comments of different quality levels, up front? Perhaps mixing Metafilter comments with those from other sites with contributors with similar backgrounds would establish the independence of this effect on comment length.

Is there something about the culture at Metafilter that promotes long comments of a certain quality level, compared with the body of commenters who participate on other non-YouTube sites? Does your hypothesis test the quality of long comments at Metafilter, or long comments on web forums in general? Doing these sorts of controls will help you focus your hypothesis.

I think you already pointed out a couple testing issues, such as your self-selected pool of voters (vote early, vote often!) which could cause a bias on results.

When doing a correlation test, you can also test the significance level of your results, to determine if you could have obtained your correlation result from random chance. It may be a matter of the luck of the draw that you obtained the results that you did. A correlation coefficient of 0.4 might look significant to you, but without a p-value may in fact have been obtained in a fairly wide region of insignificance.

"I'll bet that the first style of comment would still get a lower aggregate score."

It is probably true that length is one of the ways people decided how to rate comments. Given the same content, a longer comment might have gotten a more positive rating based on its length alone. However, if people think that longer comments are better merely because they are longer, that actually supports my conclusion that we should not force commenters to keep comments short.

"Metafilter comments originate with a very specific demographic of commenters, who are, all else the same, probably older and more educated, and who, as a result, are likely more comfortable with expressing complex ideas without regard for length within the flow of a larger conversation."

Yes. It's true that the comments I used may not be representative of comments on other sites, or even of comments on MetaFilter a year ago, or in a year.

"When a short comment is pulled at random — and what is defined as random comment sampling? — does its length ignore its potentially critical, i.e. "high quality" contribution to a larger thread of discussion?"

This is true, comments lacked context, and this probably affected shorter comments more than longer comments. For a future experiment, it would be better to look at comments that were rated in the context of their thread, for example on Slashdot.

So, all things considered, when redoing the experiment, I should:

- Use comments from a wide variety of sites
- Use ratings the actual users of the site made in the original context of the comment

Do you think that would give valid results?

If I recall correctly, The A.V. Club started limiting comment length immediately following this article, where some prick posted the entirety of the book Pinnochio. I don't know what the limit is now, unfortunately, but The A.V. Club is also, I think, a better point of comparison to Metafilter because the general tone and quality of the comments runs much, much closer than, say, youtube.

As it is, the data collected here is certainly interesting, but the overall conclusions, whether stated explicitly or merely "suggested" comes off a little bit like "after studying the body-mass index of regular patrons of Hardee's and Paul's Vegan Cafe, I can suggest that smaller portions are healthier." While that may or may not be true, the bigger issue seems to be that not eating at Hardee's is probably healthier.

Still, as I said, this is all interesting, but I think the methodology needs some tweaking.

I can't disagree with that. It's certainly true that the correlation between perceived quality and length does not occur on all sites (or does not occur on all sites to the same extent), as the YouTube data shows.
posted by L_K_M at 3:39 PM on September 29, 2009

The biggest problem, though, seems to be that longer comments will provide their own context, whereas shorter comments will rely on those comments which came before, as a general correlation. When we are asked to rate comments free of any context (and I did some the other day when I first saw this) that difference can be huge in determining how highly we rate something. I wish I had a god idea of how to solve this.

Designing your experiment procedure so as to prove your conclusion is not the correct thing to do.

I think you need to think carefully about your controls, to account for voter bias and from bias due to the source and context of the messages changing the score independent of comment length. Getting this right is critical to successfully testing your hypothesis.

You will also want to randomly select comments across multiple sites, and you will want to randomly select voters.

Ultimately, you want to procedurally isolate the contribution that length-in-itself makes to subjective-comment-scoring, as much as possible, before you begin to calculate correlation.

Once you have a properly designed experiment and have calculated correlation, you can then calculate the statistical significance of your experiment results, to determine whether or not your hypothesis can be supported by the evidence you have collected.

Offhand I would say that it is the $5 buy-in and wanting to maintain your reputation as well as Moderation and the threat of banning rather than a character limit that leads to comments that are more thoughtful and hence lengthier and ranked higher. It would be a trivial matter to write a thoughtful (long) comment and post it in successive 500 character posts.

You said: "Designing your experiment procedure so as to prove your conclusion is not the correct thing to do."

I acknowledge that there are huge issues with the test, but I most certainly didn't design it in a way that I expected would influence the results. I actually believe that the ratings are reasonably good despite of the problems like lack of context, since they correlate well with other properties I would expect to be a predictor for quality, like sentence length and spelling mistakes. Of course, it could be that people rated comments based on such properties because the comments lacked context.

At any rate, I want to make it perfectly clear that I did not intend to influence the results by my setup. This isn't a scientific study, it's a small weekend project. Most of the problems with the setup are a direct result of the fact that the time between coming up with the idea and starting to implement it was perhaps half a day. I simply didn't spend enough time thinking about it.

I ran this test because I actually wanted to know how the data would look – not because I wanted to prove my point. I did release the YouTube data, which shows practically no correlation between length and quality. I did not put as much thought into it as I should have, and I made a few obvious mistakes (like stripping HTML from comments, which probably hurt longer comments because they are more likely to contain quotes that look strange without HTML), but I did not intend to influence the results.

If I come across as defensive on this, it's because I think it's a slightly unfair criticism, and I feel kind of strongly about it. I'm grateful for all the criticism of the setup itself, you guys made a lot of great points, and if I repeat the test, it'll be much better. But I want to make it perfectly clear that I did not intentionally screw up the setup.

"Ultimately, you want to procedurally isolate the contribution that length-in-itself makes to subjective-comment-scoring, as much as possible, before you begin to calculate correlation."

Do you think something like adding lorem ipsum comments of random length to the corpus would work for that? If people rated nonsensical short comments worse than nonsensical long comments, that bias would become obvious.

"You will also want to randomly select comments across multiple sites, and you will want to randomly select voters."

A more random selection of comments should be feasible. I'm not sure how to randomly select voters on a project like this one. Any ideas?

Everything with four or more consecutive dots was included in that group. Admittedly, this does falsely include this valid use of ellipses and counts it as a mistake, as long as the writer used three dots instead of an ellpisis character "…".
