SourceForge infrastracture and services are changing a lot, and I expect SF.net to keep playing a very important role in the open source arena. But I believe also that GitHub is one of the most interesting ‘newcomers’, and I’d be open to republish its traffic graphs too.

Talking about Launchpad the greatest delusion was to sort out the hard way how it is difficult to get it running properly as an internal development system. So said, Launchpad is an open source hosting facilities with some unique features, and a broad range of projects are hosted and developed there.

PS. Launchpad inflates their user numbers significantly, it’s fairly poor metric upon which to rank the various sites. “Launchpad creates profiles for people based on Launchpad usage, as well as information collected from public sources such as bug trackers, mailing lists, public key servers, and published application translations.” - https://launchpad.net/people

Over the last years many other open source software hosting facilities are born, but SourceForge is still the most popular, followed by Launchpad, Github, Assembla, and Codeplex.
