The first decade of the current century will probably be remembered as the age when online social networking tools first appeared and thrived. And as time goes on many new features of social networking are being seen. Currently, you may have noticed many location-based tools in web-based as well as mobile social networking platforms. Now that these tools are quite frequently visited through iPhones, BlackBerries, Android phones, etc. it is understandable why these location apps are a hot new trend among mobile users. In fact, many people maintain contact through online networking while hanging out all over the place. It’s likely that users might sometimes want to communicate to their friends if they are somewhere nearby. Maybe these mobile users may want to share their experiences hangng out at a nearby venue or possibly they want to ask friends to be able to join them. Perhaps the best-known cases of location-aware social networking apps is Foursquare. Having been built specifically for iPhones, Androids, BlackBerry and other smartphones and enables users to “check-in” to many different locations. Gowalla is yet another great example. Facebook also has added functionalities such as Facebook Places, that make it possible to do the same. There are some debates concerning these location-aware social networks. Some smartphone holders feel reluctant to sharing their location with others. Say, you by mistake make known something private? Yet a great number of people that use such location-based apps believe that after you begin using it, you cannot go back. In other words, if you've ever been unsure where to go but for either reason felt shy calling, you'll be sure to love apps like Foursquare. In other words, since people can see which friends have publicly announced their location, it's probably okay to simply go ahead and stick together.
