The real question it is to know how is going to involve all social’s websites like MySpace, Twitter, Facebook or Digg’s like. In fact user lost a lot of times for going to one website to another one and can get overstress by this fact. Why going updating Twitters if I just updated MySpace? Why loosing my time with this entire websites?
In my humble opinion, I think the next version for Social Web will be an aggregator of this entire websites in just one. Just one website to update Twitters, Blog, MySpace and Facebook. I think the first starts of this future is shown by the website http://friendfeed.com/ which allow you aggregating updating from different social’s websites.
In fact, it is just my opinion… wait and see…
