It would probably be a waste. How many people would actually look up someone's profile to get that information before answering a question. Much easier to put it in the post with the question...even if it means the questioner has to be asked to come back and post it.

If it became a requirement I, for one, would feel it would be an invasion of privacy. That kind of information on a profile page makes it easy for R'osity to collect, "collate", and use for whatever. It's bad enough the "Gatesman" tries to get that kind of info from us.
