Hmmm, well the mistake that Yahoo made was identifying themselves as a portal, and that the portal was the core of their business. What they failed to realize was that the driving force behind the portal was the fact that people were still trying to find information (i.e. search). Yahoo started as a search engine that lost its focus. Did Facebook start as a "status update" site that got lost somewhere along the way? So the article begs the question: is the real reason people are driven to Facebook is to see their friend's status updates?
