This is an absolute classic of Valley bubble thinking: once you have revenues, its impossible for someone to buy you at a price totally unjustified by your present ability to make money.
I imagine the startup/VC|Google relationship to be like my first girlfriend: neither of you is sure what it is exactly you're doing. She knows if you want anything to do with her, you've got to come take it. So you're going for it, but you're pretty sure if you act like a normal dude, she'll pass you up for that scene guitarist. The only option, therefore, is to be totally aloof, so as to create enough mystery that she'll bite.
EDIT: btw, it was a pretty mediocre strategy in the long run. Not sure what that means for Twitter, however
