Just a casual observation, but it looks like AskMe's post count will reach parity with MeFi's somewhere in the next 24-48 hours. By the end of the week there will be more threads created on the green than created in the blue.
At the risk of sounding like a newbie (and my user# is embarrassingly large), I have to ask: How long do people read the threads? I often read MeFi in lurk mode, and sometimes don't get around to visiting for a day or two, at which time I will find a thread I would like to comment in, but no one else has posted to for a couple of days. I don't mind missing out on a chance to post a smartass comment, but at times I might have something intelligent to add to the discussion. At what point does posting to a thread become pointless?
So, anyone want to venture a guess as to when the number of registered users will surpass the number of threads?
yikes, Matt. what do you mean MetaFilter's filling up (note on the front page at the top right)?
