On the 16th of April every year, Foursquare Day is celebrated worldwide. The initiative to dedicate a full day to spread the love to Foursquare among other people and mainly businesss owners came from the community. Which is kinda amazing. Check #4sqday on Twitter to see how much is going around the world :) Why I am so passionate about Foursquare
Foursquare is a great service. It is in some ways still crossing the chasm, in that difficult area between being a geeky platform for the "savvy crowd" and becoming totally mainstream. Thanks to their early API access and as well as Twitter's, its arms expanded beyond their platform. So, everytime you geotag a Instagram pictures, yes, it is thanks to the powerful Foursquare data. But after 4 years, still many mobile users link Foursquare to "creepy" check-ins and "nonsense competitions" to accumulate mayorships and badges.
