Thanks to some work by Chris Credendino Foursquare Day now has a page on Wikipedia! This is great, but now the page needs a little love from Wiki editors the world over! Use your judgment to make the page strong.
Feel free to use our Press Page and the main site for reference. I hope to be putting up some more blog posts here with some more data about April 16 and well some of the ideas we have moving forward.
PS: While you are at it, the Foursquare wiki page itself could use some attention.
