I haven't taken GitHub into consideration in hiring; it doesn't matter where the source code is. Just show me that you are passionate about what you do, that you enjoy learning and can learn well from others, can work as part of a team, and that you have some code out there that demonstrates what you've played around with.

I'd be cautious if an employer wanted you to specifically have a GitHub account.

Maybe there's a market out there for "ghost developers", i.e. programmers who manage activity on the Github accounts of other programmers, the aptitudally-challenged types who need them to cheat interviews as they hop their way through technical jobs on their way to a career in IT management.
