Nah... My personal message is currently "insert emotional teenybopper song quotation here" and a friend, upon noticing it, began to explain that the fact people also put such quotes in their names is the reason he uses nicknames for his contacts.
So anyway, I don't do nicknames however, as I'm not really stuffed (and don't have the sort of personality that would lead me to consort with such persons often); and since sometimes people will talk about the formatting of their name or something, it's easier to see it and go along with the discussion than explain to them that I assign nicknames and for what reason I do so.
