My weeks tend to differ pretty dramatically.

To me, no one has fully cracked the code on social recruiting yet.

I think there are four or five interesting pockets where a lot of cool technology companies are getting started. Chicago is one of them. New York is certainly another. Silicon Valley really dominates. And you're seeing some stuff out of Boston and Seattle and down South.

Think about the way most companies currently hire. You post a job and then get blind resumes in response. This should be a social experience.
