Social Media Bubble Burst?

In an article by Carrie Brown- Smith, she talks about how 2012 may see a burst in the social media bubble. Some of the statistics that she sights are the declining numbers of people who re-Tweet, post Tweets, or that are activly Tweeting. I am starting to see more and more of my friends shutting down their Facebook accounts because they feel that it is a waste of time. Is this a growing trend in social media in general? I do not think that is the case at this very minute; however, I do think that over the next 5 years we will see Twitter and Facebook start to decline. What I am interested in is what the cool new thing is going to be for social media. I think things like Skype, where you can literally be face to face are going to have some part in the new revolution that is going to take place.
