I _hate_ that I'm so pessimistic and suspicious, and I know how important early feedback and quality technical feedback can be - BUT - I could never feel comfortable sharing a budding product in a forum full of serial founders, hungry entrepreneurs and developers that are likely in the same or overlapping spaces. The only exception would be if it was a dev tool or painkiller app where the readers here were likely the intended market.

Kudos to the people that do though - these kinds of threads are very interesting to read.
