Quoting Ryan Gonzalez <rym...@gmail.com>:
I wouldn't say it suddenly vanished, though. A quick search shows some were predicting this would happen. Lots of major projects have moved to GitHub or Bitbucket.
It was obvious it was dying when every google project started unassing the site last year. Google is huge on shoving their devs' faces into their corporate dogfood; any time a google project abandons a google product you can bet it's going to be taken out back and drowned in short order. It's still a pain in the ass, regardless of how much notice they give, but the really hilarious part was watching all of the googlers pretend they just suddenly decided their projects would be better off at github. khm
