The good ones stay away from this kind of sites. The only chance is to catch someone good and promising before he gets buried under piles of works, raises the prices and no longer needs those sites ;)
I've got encouraging comments from my customers, but dont think I am that good. (Probably/Hopefully Dunning-Kruger effect in play).

As an extra note: The Impostor syndrome is not an officially recognized psychological disorder[3]. I've seen the Impostor syndrome mentioned many times but had never taken time to read the complete wikipedia page.

also, the quality of most of the job requests is pretty low as well.
Yes and no; I would get a job, and usually lots more work would come as a direct result of that. Out of interest, once or twice a month, I'd take a look back on the site to see if there was anything interesting I'd like to work on, and if so, I would.
