Social NetworkingSocial 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.
