That's entirely perception with no basis in reality. A million users who make you $10 each are worth the same as 10 users who make you $1 million each. It's worth it for Twitter and its investors to track users so they can see how to monetize them, but if revenue goes up its okay.

If making money ever isn't the main goal of a business, that truly are screwed.

That said, I've long believed that Twitter would be one of the first to fail when the tech bubble pops. They don't have a product people are willing to pay for.
