New York City mayor Michael Bloomberg declared yesterday, April 16, Foursquare Day.
In case you don’t know what Foursquare is, users “check-in” via cell phone, telling the website their exact location. For example, if you go to Junior’s in Brooklyn, you can text or use your Foursquare application to let your followers know your precisely where you are.
The company was founded in East Village, Manhattan back in 2007, so it is fitting that this social media holiday be celebrated primarily in New York. Twelve other cities in the United States also celebrated including Atlanta and Austin. Yesterday was chosen as it was the fourth month of the year and the square root of 16 is four.
