It was bound to happen and showing targeted ads when people check-in is a no brainer. The issue Foursquare has is retaining the user base. I was an avid user for the better part of a year and then it just got tiring, it became a chore to check-in places and Facebook already had a similar feature. The badges aspect is cool, but the badges mean nothing and most of my friends stopped using Foursquare after a couple of months so there was no one to brag to and another issue is that people would cheat check-ins. I was competing for a local store that I would visit every morning and caught someone out checking in to the store when it wasn't even open and no, they didn't work there. Does Foursquare still have a large user-base left to monetise?
