Beyond Face Book

I am glad in class we got it cleared up that a social network is beyond Face Book.

People are getting so wrapped up in the Face Book world that they think it is the 'only' social network. They are forgetting that within are class we have social networks.

I know at the moment and i have not got face book and i am not short of a social network.

Anyway i wonder how long face book will last. Do you have any ideas before it dies out like the rest?

Do you remember any social networks that were once here but now gone?
