Spokeo

Social-networking sites are an efficient way to monitor friends' lives, the only drawbacks being the plethora of sites, and their annoying encouragement to network socially. Centralize your keeping-up, with Spokeo.

Spokeo's a just-launched, free service that tidily logs your buddies' updates off 30+ sites: from big 'uns like Facebook, to geek-lairs like Twitter, to more focused hubs like Flickr, to the most embarrassing of all, the Amazon Wish List (you're stupid for wanting Crocs). Just enter the trackee's email, or plug in your Gmail/Yahoo/Hotmail account and Spokeo'll extract your contacts and immediately start displaying the web-doings of everyone from "Aunt Betty" to "OilMinistersSon@nigeria.com". The resulting feed is a constantly updated superlist of everyone's most recent action, whether it's a photo upload, someone Digging Booties-4-Booty.com, or your mom's apparent displeasure with "short d*ck men".

As a bonus, Spokeo doubles as an RSS reader, automatically pulling down new content from a plethora of outlets -- handy if your obsessive blog reading's ensured you have nary a friend to track.
