hey,thanks for your comment. You are right, however, from our interviews many of them don't like to use Pinterest when they need to save and share something with clients. Lots of noise made by cupcakes and wedding dresses. Also in Pinterest you only have three private boards, while our product is totally private which, again, is better when you have clients' work. Make sense?
Makes sense. My designer and I used a shared board on Pinterest in the beginning and that worked fine. The part that got hairy was going back and forth with the actual PSDs of the design. It might be nice to add simple drawing tools for giving feedback. Good luck!
