Google seems to know how to make a splash at the trade shows, don’t they?
The hosting service is really quite lean: Subversion and Google’s own bugtracker, as well as a tie-in with groups.google.com for mailing/discussion lists. Really, though, I think this “less is more” approach is really a good thing. TestNG is an early adopter — not surprising given Cedric’s employment. While the lack of free-form web hosting could be a small issue, it is hard not to note that with just your svn server, Google Pages and Blogger, you could put together a pretty reasonable web presence for you project, though it would certainly be less coherent than Java.net or SF.net’s project page.
