Is there somewhere where founders can share and receive feedback on issues they are currently dealing with? I never claim to be "killing it" but in casual conversation if asked about my startup I'll respond with a generally positive statement assuming the person doesn't want an earful of all the issues currently running through my head. If there was a venue for this type of conversation I'd participate.
