Getting feedback on concepts

ConceptFeedback is a new Web site that offers designers a place to get feedback and exchange ideas on design concepts from other designers across the Web.

Sites like this are particularly valuable for freelance designers who don’t have the benefit of an office full of “extra sets of eyes” to look over a concept, catch mistakes, point out obvious omissions, etc. The service is free, and quite easy to use; using a Digg-like voting process and the ability to leave comments on submitted work.
