Interesting reality check 

Web 2.0, according to Mr. Winer, “is nothing more than an aftermarket for Google.” So many start-ups rely on Google — both as a basis for creating Web sites and as a channel for selling Google ads — that the entirety of Web 2.0 (the new generation of sites that rely on interactivity and open systems) will stand or fall with Google, Mr. Winer says.

“When Google crashes,” he wrote, “that’s the end of that, no more wave to ride, no more aftermarket, Bubble Burst 2.0. And the flip of this is also true — as long as Google’s stock stays up, no bubble burst.”
