This Wall Street Journal story (free preview) tracks the rise of "the snoop next door." Some highlights:PlateWire lets you connect with other drivers by their license plate numbers, whether you need to express road rage or puppy love. Caughtya lets you tattle on those who park in the disabled spot. Holla Back NYC exposes pervy Santas and subway riders. RudePeople is a repository of horror stories about cell phones in the cineplex and so on. LitterButt is self-explanatory.
