When Internet was introduced in past, it was used for 1. Chatting and voice chatting with MSN and Yahoo messenger, 2. Sending/Receiving email on Yahoo or Hotmail 3. Reading news on news portals. Now we can see that all these features are available in a single thing called Facebook. We can send messages, do chats and see latest updates on news, so can we say that Facebook itself is a unique entity and it is a newer version of internet, can we call it Internet-2 ????
