Last year, around the start of South by Southwest (SXSW) 2010, the idea for Foursquare Day was born and the countdown was on. Just a few weeks after the idea was hatched over 300 cities joined together to celebrate 4/16/10 as Foursquare Day! To celebrate the anniversary of the start of Foursquare Day we’re gathering one year later at the start of SXSW 2011 in Austin, Texas on Friday March 11th to officially kick off the countdown to 4/16/2011, Foursquare Day 2011– and we want you all to join us, even if you can’t be at SXSW! Here’s how:

We’re inviting everyone to create a short 15-30 second video greeting to celebrate the kickoff of the countdown to Foursquare Day with your name, where you’re located and what you’ll be doing to celebrate Foursquare Day. Please post your video to YouTube and leave a comment on this blog post by Wednesday the 9th with a link to the video so we can know where to find it. Then on Friday we’ll have a special Ustream broadcast (time and channel to to be announced soon!) for everyone to tune into as part of the event at SXSW. During the broadcast we’ll share some of the best videos!

Watch this video shot at Foursquare Day HQ South earlier today by Foursquare Day founder Dr. Nate to get an idea for the kind of video we’re looking for and to learn more about how you can virtually take part in the kickoff event. Then we’ll see you in Austin on Friday, virtually or otherwise!
