You can get at a wide assortment of people, before they have been tainted by any other offers, at colleges for interns. If you get them early enough they will be happy to get the work experience, and you can find the really, truly bright competent people before they gets sucked up by another larger company like Google. It gives you a much better pool to look at when you're looking to permanently hire then the people who are looking for a job with experience. (they're looking for a job for a reason, they're not the best out there)
There was a really good article about this in Inc. magazine a few months ago, maybe it can be found online.
Oh yeah, and gimme a job lol.
