The "I just don't get why you'd want to check in" crowd just got their answer. Foursquare was a cool app before, but this new version makes it incredibly useful.

The "Explore" tab (basically, recommendations based on your friends and people who go to similar places as you) is a total mobile Yelp killer- at least when it comes to quickly looking for somewhere nearby.

I love when a company keeps innovating like this.
