As some of you may already know, April 16th is Foursquare Day. To encourage their fans around the world to get together and celebrate this event Foursquare has created a special badge and logo for this 4sqday. So we can unlock a 4sqday new badge by checking in on April 16th!
Foursquare has also created the official event on Meetup to help local communities plan their 4sqday.
Here is a meetup event planned for Paris: http://www.meetup.com/foursquare/Paris-FR/87940/
Some cities (unfortunately, not Paris) even officially proclaimed April 16th, 2011 as Foursquare Day. But anyway, we were happy to see that Paris was the first European city to get over 50 people signed up for the 4sqday meetup event.
At Mapize, we are big fans of 4sq, so we participate in organizing this local 4sqday event in Paris.
There are currently 70 "Count Me Ins" for the meetup, and all those who are in Paris on 4/16 are welcome to join us!
Stay tuned for updates on meetup !
