I recently checked out the Ban.jo app based on @wsellers recommendation. This app shows the latest updates for Facebook, foursquare, twitter and instagram users in your area. Even if you are not friends with them you can see their posts on these social media platforms. It freaks me out a little. Can you hide? I’m not sure.. One thing you can know is with this app someone may be watching you. Stalker app for sure. Why in the world would they create this app?
