Philly Celebrates National Foursquare Day. Are you checking in today? The tech-savvy in Philadelphia certainly are. April 16 is National Foursquare Day (you see how they did that? 4 squared equals 16), and Philadelphia is celebrating in its own unique way. National Foursquare Day is when communities plan events or lectures to encourage mass check-in’s on the service. Believe it or not, foursquare spans over 15 million people worldwide, according to January statistics.

Foursquare, for those unfamiliar, is the location-based check-in service that alerts friends to your whereabouts. More than that, they offer specific discounts at certain venues based on your check-in activity (and if you link up your account with your American Express card, even direct discounts to your monthly statement).

To celebrate the big day, the marketing folks at Visit Philly have put together a foursquare list of 16 places around town that involve a “square” (from Washington Square to Squareburger and more). At one of the 16 locations, they will be giving away a prize at 4:16 p.m.

Additionally, the folks at the Social Media Club of Philadelphia along with The20’s @anniemal (among others) have organized “The Philly Foursquare Games,” a Hunger Games-like competition of squarefour, the popular game we all remember from when we were kids. Their event takes place at 7:30 tonight at the Marion Anderson Recreation Center and it is free to attend (though the teams are already set).

Oh, and a quick plug: don’t forget to follow NBC10 on foursquare.
