I hate to put it this way, but what are you doing on HN? Seriously.

I apologize if I offended you, Ryan. All I am asking for is for an example of one company that had reach the sort of mass FB has (coupled with a total dominance in its vertical)and ended up loosing to a competitor. Enlighten me.

Yahoo

Yahoo was a portal that was made "irrelevant" by Google. Google was not in the portal business. This is what happens when a company comes in and changes user behavior. In other words Google did not build a better portal, they build something that made portals irrelevant over time.
