I still have 17 minutes of free time in my day... what should I do?

We spend endless hours on Facebook and Twitter. We sit in the Starbucks line Tweeting, and our breaks consist of looking at recently posted pictures of friends. But is there a new site that will sweep us off our feet? Has Foursquare crossed your path?

This site – which you can get on your mobile, of course – allows you to tell people where you are by "checking in." By checking-in, your friends can find you, and you'll receive recommendations on the hotspots nearby – bars, restaurants, coffee shops, shops, etc.

Do you have a list of favorite places or know the best thing on the menu? Foursquare helps you keep track of your to-do lists, and it'll even suggest new places to check-in to. These lists can be seen by other users so a wealth of knowledge and secret discoveries are waiting to be uncovered.

You also earn badges. The more you check-in, the more people you hang out with, and the more interesting places you go, the more badges you'll earn. You may eventually achieve the "mayor" title for being the most loyal "regular" to attend a local hangout – and even earn freebies from the place!
