Below the ten most popular Foursquare badges, and also ten of the most easily obtained badges. Something I wish Foursquare would implement is listing the requirements for locked badges. That would make it that much more fun. Gives you something to achieve. Right now you just happen to unlock a badge at some point, without having the feel of having actually achieved something. That, at least, is my opinion. Of course there are plenty of websites/blogs out there listing the requirements for a ton of badges, it would just make more sense to implement that within Foursquare, in my opinion, again.
