You&#x27;re mostly right. There is a lot more sophistication now, but most of the advances facebook has made are in two areas:<p>-Mobile. Making messaging a central strength of the platform. Figuring this out is a big piece of why the stock is doing so well.
-Conversations. Facebook has become the default place for people to discuss (or, more accurately, shout about) media&#x2F;news. I mean both news from external sources and personal life events.<p>Everything else is reorganizations of existing features in new ways, like the shift from the wall to the timeline. It was a new feature that better fit an existing goal, not an expansion in the scope of the service.
