Social Networking, thing of the past?

there is one thing about social networking, it is not a guarantee it will stay around forever or in a better term: stay the same. I have noticed over the years how many websites like myspace and facebook change to keep up with the pace of society and keep many people interested. I wonder how much more could they possibly change before they become obsolete to something else? There could be a whole other form of internet socializing soon to be made! We have no idea...other than technology is rapidly advancing. I feel it is only a matter of time before these internet sites like facebook and myspace will become a thing of the past, much like how listserv was treated. People move onto bigger and better things now. I guess it is a wait and see if Social Networking sites will last or not. Hmm...
