We'll consider it ;) I think Github and Stack come close, but there you still need to know what you're looking for. InterviewStreet does a good job at pre-filtering candidates. Non-the-less, we'll keep that in mind!

Check out yunojuno.com. Similar, but different. I know the guys involved and they are hoping to build a community of freelance designers & developers, using peer recommendations as the glue. In project-led business (e.g. agencies), the 'Hollywood' model of bringing together the right team at at the right time _should_ prevail. That's what they are hoping to enable - giving power / control back to the freelancers themselves.

That'd be especially useful for when you're looking for consulting gigs and other temporary projects. I'd use it :)

What about Elance?
