So you already spend all your time on Facebook—that's not enough for the social networking giant. Soon, it will want to know where you spend all your time (in the real world). Over the weekend, TechCrunch identified a glitch in Facebook's mobile site that allowed them to see a space for a new feature called "places" being built in the code.
Based on the code, this is what it seems that Facebook is about to launch: A mobile version of the site using the HTML5 location component to grab your location information from your phone. Once it does that, you’re taken to this new Places area of Facebook that presumably will have a list of venues around you. From here you can click a button to check-in. Yes, there will be check-ins [TechCrunch].
