So this site just wasted 30 minutes of my Saturday.....and I really enjoyed it.
The New York Times has taken Netflix queues from several metro areas around the country and done highly interactive maps of which movies are popular in which zip codes. It's a fascinating look at how much similar tastes seem to huddle together (even more than voting patterns, it appears). While some movies are popular everywhere (Benjamin Button), others are wildly different (Mad Men; Paul Blart: Mall Cop). Check it out!
