I found this fascinating quote today:
The website as we know it is becoming a relic of the first 15 years of the Internet. Sure, websites will always be important, but the action that takes place around a company, brand or individual is moving into a complex web of stateless conversations. Some of these take place on corporate websites, but many of them don’t. Consider Facebook, whose 200 million members are the world’s largest ready-made audience. Some brands have more active communities of customers on Facebook than they do on their own websites. In fact, their own websites may not even enable community at all. Perception of their brand is defined in a community that they host but can’t control.Fredzimny, Fredzimny’s CCCCC Blog, Jul 2009
