Then why the IPO, except as an exit strategy for the founders?

So Zuckerberg cashes out at Facebook's peak, leaving the subsequent 'investors' with nowhere to go but down. I wouldn't necessarily put that intention past Zuckerberg, and perhaps a Facebook collapse would be a good thing for openness and interoperability on the web, but isn't it a bit of a self-defeating strategy? Can the hype machine generate enough naive investors to generate a substantial cash-out?
