It was always my opinion that Github's killer feature was putting repositories under user namespaces. Its hard to imagine but before Github you had to ask SourceForge politely if you could have a given project name. Just the ability to make your own projects without needing to ask anyone seems so obvious now, but really was a game changer at the time. This is also then deeply tied to the idea that forking repositories should be easy. I'm glad to see that the article includes this in their history.
