Summary: I just updated the Hoogle website. It looks nicer on the iPhone and the source is on GitHub.
The Hoogle website is (as always) at http://haskell.org/hoogle. I've just uploaded a fresh Hackage index (currently a manual operation, but one I'm intending to automate imminently). I've also made a number of improvements if you are using Hoogle over the iPhone - to simulate the iPhone experience click here.
The source code has moved to Github: https://github.com/ndmitchell/hoogle. While darcs is a much nicer version control system than Git, GitHub offers a lot of nice features, so I'm using Hoogle as an experiment. I've been promised that projects on GitHub get lots of contributions, so now I wait!
I'm leaving the bug tracker in Google code for the moment, and am considering where the Hoogle manual should live, but a GitHub wiki site is currently looking likely.
