Exactly. And that's why I'm right. Facebook isn't a generic solution, like email. People don't use it for business, for example. It also has a strong branding and part of that is in terms of "coolness". Now it is something that your mom uses. How long do you think the early adopters -- students and teenagers -- are going to put up with that before it gets organically rebranded as uncool? And, as we know from the Diffusion of Innovation, if the head of the snake dies (the early adopters go away or go somewhere else en masse), it's only a matter of time before it, well, becomes MySpace.

Google ... trying everything and excelling at nothing

That's it. Hot startups are like child stars. If all the idolization seeps into their ego, you can guarantee they'll be shooting porn by 20. Why? Because they think they're entitled to what they have, but what they have will change. And their sense of entitlement means they won't take the change seriously and even as they watch it go away, they'll just assume it will come back. Google has a serious case of the egos. It doesn't matter how many people love them now -- they don't stand a chance.
