People
As online photo memes go, "These are the People in my Neighborhood" is simple and cute. Twelve lines of lyrics (well, if "bor..." counts as a line) plus twelve people on the street equals a tiny glimpse into a town.
Only two neighborhoods so far (India and San Francisco), but with the Powazek's playing, I'm sure it'll catch on. I'd do it myself... but I think most of my neighbors already think I'm too weird to bear.
