The biggest feature that Github provides is its popularity as a central meeting ground for project discovery and collaboration. Some people are only looking for git hosting and don&#x27;t care about the community aspect, so they could jump ship to Bitbucket or Gitlab.<p>In that respect, if you&#x27;re looking for a social network to keep in contact with a general group of people, Facebook is the way to go, and not the myriad of smaller sized social networks. If you&#x27;re only looking for communication with a small group of people who haven&#x27;t committed to anything, then you could jump ship to Google+ or whatever. Size of community is the salient feature, not the app.
