I've used it extensively as an employer. I've found a few real gems that I would love to hire full-time someday, but lately I've been having a very hard time finding quality talent. I've had four hires in a row that accepted the job and then completely dropped off the face of the earth afterwards.

I've also run into quite a few contractors who lie about their skill set--hoping, I assume, to get ANY kind of work and then learn it as they go. It makes ramping someone up kind of frustrating... but once you find someone good to work with I've had nothing bad to say about it.
