In my love of maps and demographically-oriented things, the CommonCensus Map Project is pretty neat, if not entirely scientific. It allows you to enter your address and determine the major city which influences you, as well as local neighborhoods. It is partially a protest against gerrymandering, but it's also just fun to examine!
And, after next Thursday, I'll blog more, I promise! I have 3-4 posts rolling around in my head, I just haven't taken the time to do them.
