Sun is a huge company. So it comes as no surprise that I’m finding out about Project Kenai via Tim Bray, instead of some internal mailing list (believe me, there must be thousands).
Tim’s got a Q&A with Nick Sieger, who’s one of the chieftains behind Kenai. I find it amusing that the comparison is made against Google Code and GitHub - has SourceForge hit irrelevancy? I’m surprised Launchpad isn’t mentioned.

Very Cover Flow like UI, with slider, etc. That’s Elliot Murphy, ex-Dolphin, current Ubuntero in the pic
