You can kill facebook by disintermediating their primary feature -- relationship management.

Stephen Hawking could have said "one's greatest strength is also one's greatest weakness." But he didn't, even though it's true for companies like Facebook, whose greatest strength -- a singular feature of their site -- is also their Achilles Heel. The hallmark features of online services have emerged one by one, and at each emergence a new giant company is born. Compuserve's initial MicroNET consumer service exploded as civilians discovered eMail. AOL grew to giant proportions by adding consumer content and discussion boards in a graphic interface, followed by the rise of Excite! and Yahoo and the other search engine-based services like Google.
The era of MySpace and Facebook added relationship management (your lists of friends, suggestions for additions to the list, etc.), and grew rapidly as social media became an addictive behavior among consumers.
However, like eMail, Facebooks singular advantage -- relationship management -- can be replaced by a widely distributed mobile and desktop app which would hijack and localize the list coordination utility.
