Foursquare – an awesome location services that I use way more than I should – announces the release of Version 3. They have a lengthy blog post explaining their reasons, goals, and changes. And I have to say that it’s exciting. I was slightly worried that they might give up given the Google Latitude check-ins competition, but apparently they are not. Good for them! Anyways, my phone still runs Android 2.1, so the newer Latitude is not available to me. But the new Foursquare is. And there is plenty of new fun, including leaderboards and Explore.
