I want to know, but do not know, what other people think of me; which of my traits matter to them and which don't; what determines their reactions to my words and deeds; and how a person can learn such things in general ("just asking" obviously doesn't work). For looks we have sites like hotornot with anonymous reviews and ratings, but what to do about personality?
In most cases they laugh it off and say it was nothing but maybe in some cases it does help, I dunno.
