As others have stated, how well someone codes is less important than how good a cultural and personal fit they are for the company. I want to know how passionate someone is, how well they do when pair programming, how well they communicate, etc in addition to knowing how well they can code. I can teach someone, who is willing, how to be a great coder, but I cannot teach someone how to fit well into the company culture or with my team.

In addition, I know too many developers who I would hire in a heartbeat that do not have repos on Github and far too many developers that I never want to work with that do have repos.

I also find it curious that on http://githire.com/order, when I refresh the page and see people like 37Signals and Omni show up. Not sure they are looking for new gigs.
