360i Fires Up Tweeting Keg for Foursquare Day

Today is 4SQDay, the day location-based social network Foursquare hopes to reach a million users. For math nerds out there, the number 4 squared equals 16–the 16th of April.

Digital agency 360i is dusting off their lonely Twitter-enabled keg (just 5 check-ins so far) in celebration, and hoping to unlock the Swarm badge (50+ check-ins at one location at the same time). You can both check in at the tap, or with the tap.

Free beer begins at 4:16 PM (of course) at the company’s headquarters on 23rd Street in Manhattan. Direct message 360i to RSVP.

Create a social media strategy, launch your campaign, and track the results in our Social Media Marketing Boot Camp starting February 16. The online event and workshop will feature speakers including The Onion‘s Baratunde Thurston (left), Facebook’s Morin Oluwole, and bitly’s Tim Devane. Register now.
