Been discussed here as recently as last month.

Like anything else you get out of it what you put into it.

I had a need for a specific skill set and rather than advertise for the position I popped my requirements into Linked In, filtered on my geographic location, found some candidates, one in particular that seemed very promising. Called him first, hired him the next day. In total it took less than a days effort from start to finish and the kids a superstar.
