Soon, Facebook Will Know Where You Are Social networking site readies location-based technology By Evann Gastaldo, Newser Staff Posted May 7, 2010 12:18 PM CDT 10 comments Comments Madisonville Mayor William Cox replies to question posted on his Facebook page with his iPhone Thursday, Feb. 5, 2009.

Patmore) (Newser) – The latest evidence Facebook is trying to take over the world: The site will soon launch geolocation applications, directly competing with Foursquare and other location-based social networks. What does that mean for you? Soon, telling all your friends you’re at McDonald’s will be even quicker and easier. Mickey D’s is one of the first marketers planning to take advantage of the new service, Advertising Age reports. The McDonald’s app will allow users to “check in” at one of its locations, and when that status update appears on your Facebook wall, it will be accompanied by a featured product like, you know, a Big Mac. Classy. But even if you’re not a frequenter of the golden arches, you’ll still be able to include your location in a status update—and apps from other companies are on the horizon.
