Exactly. If it ever becomes necessary to move away from github, it can be done in seconds by adding a new remote and pushing. I have always seen this as a testament to github's quality - if the switching cost to your users is a couple of shell commands, you better make sure you offer a good product! I also keep my projects in a local gitosis repository, mainly so I'm not relying on github as part of my deploy flow.
