Collaboration Website

Hi everyone,

Does anybody have any experience with the Behance (https://www.behance.net/) site? I was thinking about becoming an active member, but it takes a lot of time and effort, and I would like to know that the time is well spent. The site is part of the Adobe Creative Cloud, so the basic service is free with my subscription. It seems to be more dedicated to commercial graphic art, rather than fine art or even stock photography. However, if it can be a source of effective, constructive feedback from professional artists, it would be well worth investing the time to become an active contributor.

Thanks in advance for any input.
