You have precisely identified the bubble, inadvertently:

Why are we determining what these companies are worth based on things like number of uniques and users, rather than the actual amount of revenue they bring in? Users, in-and-of themselves, are useless. Revenue is always and everywhere the end goal. Somehow we've begun to take at face value that more users=more money, and I don't think that's the case.
