You can no longer afford not to take Git seriously

For people coming from client-server SCMs, I think Github is a really important transition step, and frankly, as an open source developer and consumer, it's really nice that there's a popular publish/find-stuff hub.
In fact, I think the blog post here reaches the wrong conclusion, in that everything he thought about using git is actually (still) true, but it is widely successful anyway because of other projects (mostly related directly to GitHub) which hide the complexity of git from the "9-5" developers.
