Are you too old for Social networking sites ?

In a recent interview with BBC News Tim Berners Lee who is considered as the father of internet answered a question, Are you too old for things like MySpace and Facebook?. For which he responded that “I’ve seen no evidence - either from my point of view or anybody else - that social networking and generally using the net to interact with other people is something that’s restricted to young people. In fact it’s very popular with older people. Young people can get on their bikes and visit each other, older people can’t. It may turn out to be more important for seniors than for young people.” I agree with Mr. Berners Lee and feel that the value of online social networking tools to a productive adult is immense, whether it is getting ahead in his career, keeping his hobbies alive and kicking, touch base with his school or college mates, Increasing participation in real world social communities etc.. In a broad sense being more productive in what he or she is doing today and achieve goals. But all the sites which exist today have been designed keeping mostly the entertainment value in mind with notable exceptions like Linked-in. Also the real world communities which a productive adult participates in, is either not online or are fragmented across various sites or applications spread on the internet. Then there is a clear lack of seamless experience for the user. It is quite a challenging task to keep up with the flood of information and trying to find the relevant one.  The idea of getting the most relevant information pushed to me when I need it would be the holy grail. All this will require first to create a solution which looks at a person’s real world identities and then give him/her the tools to manage those.
