Lately I get all of my projects directly from customers who approach me first and these project have nothing in common with the stuff I find on those job boards or get offered by recruiters. The projects I get directly are of much higher quality that the public offers, but I also ask myself how much such numbers reflect reality. I mean the dark figures could be totally different.
