I think if I make any polls which actually have a point beyond arbitrary random interest (like "How do people's opinions on X topic vary depending on what region they're 'from'" etc) I'm going to have to think very carefully about which of those (or other identities etc) is relevant and how to ask about it. Location seemed like a good place to start with since it is at least fairly easy to answer for most people but it obviously doesn't tell you very much about a lot of things.
