We all understand the value of social networks. They help us find jobs, apartments, even friends. Online social networks allow us to connect in the same way but geography is no longer an issue.
One of the most popular sites, Facebook, allows us to stay in touch with our friends, and find new ones, from all around the globe. Another example is LinkedIn, which helps us to discover jobs, business opportunities and get expert advice no matter where we are. Even online photo sharing sites, like Flickr, have groups based on specific interests. These kinds of sites allow us to focus on our interests and not on our location.
