What happens when a social service truly catches on and everybody signs up for it? The answer is always the same: we see the emergence of systems for measuring who has more “authority” than the rest. It happened with Facebook, it happened with Twitter, and now it is happening with Foursquare.
That is only natural. For worse and for better, society is structured in layers. If these are not maintained in services that have a social aura then the whole system feels unconnected. And while the dilemma of who is more powerful or influential in Twitter is still to be solved (Is the most influential user the one who has a trillion followers? Or the one who gets the biggest number of retweets?), a service like Foursquare is entirely different. Foursquare users have a hierarchy by default. They actually “compete” to become the mayor of any location. And that is why a grading tool like the one being reviewed right now is more than viable.
Named SquareGrader, it will look at your stats and at the performance of your friends in order to let everybody know who is who in terms of popularity by giving out individual scores.
All you have to do for this score to be unlocked is to sign in using your Foursquare credentials. That’s basically it. At no point are you asked to disclose any other type of information, and you are not charged anything either.
