Social networking and blogs have now become more popular than sending personal emails. The idea behind these sites is that of global online communities. To join a community you need to create a personal profile. Then you can connect with your friends, share pictures, music and your thoughts. Social networks are not new but they are evolving. Almost all the networks can now be accessed from a mobile phone. Sites seem popular with a broad audience largely thanks to bolt-on applications which allow everything from photo-sharing to online gaming. Whether this is a clever public relations stunt or a means of directly communicating with friends or fans, it is undoubtedly fascinating social commentary. Of course, there are those who fear that these online communities may in fact be anti-social. They are anxious that the more time people spend on these sites, the more difficult it will become for them to communicate in face-to-face situations.
