This year marks the second annual 4sqDay and foursquare's second birthday. foursquare says, "We're so touched by the support we get from the over 8,000,000 people in the foursquare community, and love that 4sqDay has bloomed from that."
If you aren't familiar look at the The Foursquare Day Story, last year, a group of foursquare users in Tampa dreamt up a fun new way to connect with all the other foursquare users in their area. Marking 4/4^2 on their calendar, they declared the first foursquare(d) -- get it, four squared = sixteen -- day, 4/16. As word spread, nearly 300 local 4sqday parties took shape, from Kansas City to Kuala Lumpur."

Foursquare has created a special badge and logo for 4sqday!, and will be sending out kits -- filled with stickers, pins, and banners -- to organizers with large gatherings planned.
Details on exactly how to unlock the badge has yet to be revealed, but stay tuned! Foursquare has also designed a limited edition T-shirt to celebrate 4sqday 2011, which's now available (at 40% off!) at the foursquare store.
