To an extent, projects that lean more on github tend to receive more github stars. I don't know when numpy switched over to github, but their website still uses SF to distribute the official binaries. On the other hand, many projects initially started as github repos and naturally draw people that way. As an example, consider d3, where the main page rests on d3js.org but most of the links point to the github project wiki.
