After I read some questions and answers about common courtesy rules in math and in particular on this side, it appeared to me that maybe the best courtesy advice here would be "Keep math in the foreground and yourself in the background". This seems reasonable to me, but my question is to what extend? Clearly, if we could loose our personality at the door when entering a seminar room and just try to think about math, this would be good for various reasons: it would increase the effectiveness and decrease the possibility of being rude/discriminating whatsover. BUT: we are still humans. I read in a post here that there is kind of a question whether to make a "thank you" note after a question or not. And, to be honest, I don't really care about the answer, because is this question really what mathematics should be about?
So my question: How much of my own personality can I inject into my mathmatics?
