I was recently listening to a podcast (Freelanceswitch Radio) and they were discussing getting jobs from websites. The general conclusion was that if you are in the market to be a "serious/full time" freelancer that online jobs were not/will not be a main resource. Online jobs were a "filler" when people had time to surf the net and apply when regular business was slow.
I have not had any personal experience with either.
