I don't think MeFi is too big.
Yes, it's become impossible to follow every thread.
Yes, some users are idiots (no, not you).
Yes, some topics have been beaten to death; yes, some threads collapse into pointlessness.
But I come to Metafilter tp be exposed to interesting information from a diverse group of people; that was why I first started coming here a year or so ago. I sift through the day's posts and look for the ones that seem the most interesting. Metafilter is not a "pre-sifted" environment, like, say, a moderated mailing list — but, for me, the value of Metafilter emerges.
I've always had to perform sifting here. Even with the increased number of posts, the effort required to sift takes me no more than one minute per day. More posts means more bad posts, yes, but I find that it also means more good ones; and that seems true in the discussion threads as well as the main page.posted by jbushnell at 9:26 AM on May 17, 2001
