I'd enjoy a conversation with anyone who thinks they have a useful comment (on any topic) which is un-postable because it would be received negatively. I'd like to explore whether it's about avoiding negative karma points, or fear of unkind followup comments, or wanting their user page to have only "important" things, or something else.

I'd like to have it in public, though - if you fear any of these things (or other reasons I haven't thought of), make a throwaway/burner account and use that.
