Facebook News(feed) Flash

Besides the obvious user experience improvements, greater flexiblity for advertising for facebook, and general polishing -- the new design also signals an interesting move by facebook with its new empahsis on the feed: Control.

With the new user experience emphasis on the newsfeed, not only does it enable more interesting user interactions, but provides facebook with a way to have greater control over how its applications connect with its end users.
