as is transparency in discussions of a "collective" project in a forum where an idea is collectively being developed.

the degree of productivity is dependent on how the feedback is acted upon.

you wanted contribution to your idea - you got it. not in the form of unconditional positivity you wanted. but in honest, authentic, objective feedback. maybe I offered too much too soon when it wasn't asked for, so my bad.

OR on the flip side - it could be a challenge. and rather than getting defensive and shrugging it off, you could use the questions to stimulate an elaboration into the details missing from your first take to clear up the misunderstandings generating the feedback.
