I don't know how successful they are, but if someone did that for my company I can say for sure that I'd certainly give that person some serious time and consideration.

It's also not really an HR thing, IMO. It's almost a "bypass HR" thing - it's so much better to have the devs/designers/whatever coming in to work and saying "there's this great person we should hire". Impress the people you'd be working with - not the ones who work tangentially near them!

Makes me wish I was in the position to offer roles - just the act of getting off their arse and doing something like this is a great start from anyone.
