After Facebook Graph Search announcement, new discussion of privacy

Earlier this week, Facebook CEO Mark Zuckerberg took the wraps off a Facebook search feature called Graph Search, which harnesses data from your friends' feeds and turns all of Facebook into one giant recommendation engine. Want to find Star Wars fans in your area? You can have that too. "You can find people based on things they've shared with you, including their interests and profile info," Facebook reps wrote on the Graph Search promo page. "You'll see results for friends who share their city with you, people whose city is set to Public, and suggested results based on info shared with you."
