Future Of Social Networking Sites

Social Networking sites are getting popularity day by day. There have good numbers of sites which are very popular and some are really very helpful and creative. We spend huge amount of time on social networking sites. But the question is are those sites are really helping us to be more social, are those sites really helpful ? 

Specialist people are concern about the increasing popularity of social networking sites. They are concern because kids and young people are spending their leisure on those sites rather spending time with real friends and family members. People are making friendship with unknown people and share their secret things with those virtual friends. On the other hand they do not have time even to say their friends at least "hi".

Of course some of the sites are really very helpful. But still we are concern. In future what will happen ? I think we should start working with this thing. There should have some rules and restriction for kids.
