Here's an article from the Chicago Tribune that gives a little more backstory on its resurrection: http://www.chicagotribune.com/business/breaking/chi-everyblo...

Comcast acquired NBC recently, and with that came NBC's assets, one of which was EveryBlock (which NBC had only recently acquired and then shuttered).

Comcast brought it back -- not under NBC anymore, but under Comcast proper. The big question is why? What is their monetization strategy? As a Chicago resident and past EveryBlock user, I'm very curious about this. My first guess is that Comcast appreciates being able to correlate an email address with a neighborhood, for marketing opportunities.
