Github Pages are really useful. Maintaining a project site is really easy when you can just create a gh-pages branch and push to it to update your site.
Also, network effects are undeniably part of the appeal. I'm much more likely to hack on a project or library if I can fork it on Github. It makes for a nice workflow.
