This is where meetups could be useful. Roux and I have to depend on being as specific as possible. However, at a meetup, you could poll the group for their honest opinion.

Just an outline of what I'm pondering:

It would be like a silent auction, where everyone submits a 'what do you think about me' question.

A question is drawn, the group answers the question, everyone is embarrassed, next question.

Sounds like fun, actually. It seems a bit like 'truth or dare.'
