I agree to a point. The point where I start to balk is the implication that once people start leaving there's nothing the 'hosts' of the party can do to turn things around again. This isn't necessarily true. Break out the top-shelf booze, as it were. Step up your game, do something drastic. Going back to the web reality of this conversation, obviously you add V, if you can think of a way to do so. I think facebook is hoping that they can leverage their developer network to increase V and that the introduction of efforts to monetize won't reduce V so drastically that 'death spiral' occurs.
