The Status API, how we clone quickly, the entire signup workflow are all built around Github. We have special logic for github downtime, retries, handling 3rd party repos, collaborators, etc. For example, we dont have usernames or passwords or password resets for Circle, we just have github oauth. We don't have teams, we just mirror the github permission model. We don't verify your email: github does it. Most importantly, when you sign up, there's a great flow. You give us oauth permission, and pick a repo (we have a list because Github) and then we can have you running tests in seconds. We automatically fiddle with Github to make that work (you dont need to add post-commit hooks or ssh keys, it just works).
