So, it's obviously not for talent ($100mm per head? no way...), users, or tech. That leaves it as a competitive play. They took Instagram off the market to keep it out of the hands of Apple and Google.
Given the "prices" Google are rumored to be paying to acquire great engineering staff, a team of three engineers who've got a proven track record of building and supporting 100million users on their own - surely they'd be worth some not-down-in-the-noise-floor percentage of even the seemingly insane valuation here?
And a founding team who've "created" $1billion in value in ~550 days? Even if you only credit them with last weeks $500mil rumors - surely that founding team would be worth several tens of million dollars even if you didn't get the company they founded?
Darn-it!
