SourceForge is making the most fun of migration from #GitHub. The stuff most important to them is listed right in their site header: "Cloud Storage", "Business VoIP"... Then a nice set of social media buttons: twitter, facebook, google, linkedin. And right below that, a "Migrate from GitHub to SourceForge" banner, welcoming people who run from "proprietary" GitHub.
