This kind of sites have the problem (big one IMHO) that the projects descriptions are almost useless as specs, and a lot of developers don't know how build that from the customers (and rarely a customer know what to say, ask or give). I wish that when a customer send a project, somebody review it and check if the assumptions of the customer are on line with reality, or can do some consulting to properly scope the projects before div in. Probably having projects manager in the side (not in the middle!)?
