Something for FB fans who are are unsure how much location data their are sharing… Facebook users can easily access their entire location history. Essentially, this is all the places where you use the facebook “checkin” feature.
To view these data jump to your profile, hover the mouse over “More” and click “Check-ins”. You can then view places, cities and recent checkins. The results are displayed on a map where you can then jump directly to the data you shared about the location. Unfortunately there doesn’t appear to be a way to access the raw data and download it for further consumption.
