Title is misleading. No documentation of a tech bubble. Mostly a rant about social sites that haven't yet developed their business models (monetized themselves). It's valid to be concerned about monetizing a social app, but... do you remember all the static that Amazon received for years about not turning a profit. But they built their base and a supreme market position. As of December 2008 Amazon was one of few online retailers to grow! Be careful about the generalizations. Or the assumption that you can't later bring in the business types to ramp up the marketing and cash-flow aspects. Timing is everything. And is easiest assessed in hindsite. Not to say that Facebook/Twitter don't need to seize that moment now... Just to say that some "bubbles" make good molds on which to build solid financial models.
