I’ve had a Forrst account for around 3 weeks now and I think its a fantastic service to use! I was a bit hesitant a first, with the type of feedback I would get and whether anybody would actually give feedback! I’d use Twitter at times for things I was working on, and never got any real answers or any answers at all maybe because of the platform! But now, not only do I feel better off as a designer for posting up “Snaps” I’m currently working on and getting very constructive feedback, but viewing and commenting on other peoples work makes me better off in my approach to responding and my thought process in designing work for myself.  I would definitely suggest signing up to request an account or try and get invited by somebody.
