This is the community weblog that gives crowdsourcing a good name. Every day, MeFi (as it's known to fans) posts a dozen or so detailed items (with copious links) on subjects that users thought interesting enough to share with the rest of the class. The result is a ludicrously diverse encyclopedia of surprisingly useful and shockingly useless knowledge the latest findings on string theory and evolutionary biology share space with fond remembrances of the TV show Charlie's Angels and rumors of a new Spinal Tap album. Plenty of blogs traffic in pop culture ephemera, but Metafilter takes it seriously. A recent online food fight over whether the lead character in the old Road Runner cartoons said "beep-beep" or "meep-meep," was finally settled by a MeFi contributor who once had dinner with the cartoon's animator. The verdict: Meep-meep. Now you know.
Sample Metafilter post: For the last few years across Melbourne, a mysterious, box-like man has been appearing. He is known as Crate Man.
Entry you'll never see: I was going to share a detailed history of miniature golf with everybody, but it seemed too trivial to post here.
