A popular social media app is called Four Square. Four Square allows us to check in to different locations and become the "mayor" of a location if you go there enough. Though this app is popular, it could be extremely dangerous. By checking into locations, you put your information out to the world that you may not want everyone knowing. It allows potential dangerous stalkers to follow you and possibly find you. Social networks can be great, but when it comes to some like Four Square, we must be careful about the information we share with the world. The Internet is fun but it can also be extremely dangerous and we must always remember that our safety has to come first.
