Inthe past week since joining foursquare I have collected 3 badges. I did not think this would happen as fast as I am getting used to the application. I have received the Newbie badge which was for my first check in on Septa bus line at 8:17 am, April 14th. I received the 4sqDay2011 badge for being at The Vault Ultra Lounge at 11:02 pm, April 16th. This one was more surprising because I had never been to the lounge but I know of many people who have. The 4spDay badge represent 4/4^2 = 4/16. My third badge is the Adventurer badge for checking into 10 different venues. I unlocked this badge at the Wing Stop on broad street at 3:35 pm, April 21st. I am excited to see what other badges I can collect.
