You can come out of your bomb shelter now -- the Twitpocalypse didn't happen! Mostly.

What am I talking about? My colleague Sean Michael Kerner maps out the glitch-that-mostly-wasn't that had been widely feared (well, "widely" among the kinds of folks who live and die by the microblogging phenom,) but for the layman, think Y2K for Twitter.

(You can also get the gist of the technical discussion here.)

The real story, however, is how widespread the hysteria reached. But I suppose these kinds of mass online panics aren't anything new in the Web 2.0 era -- nor will this be the end of it.
