The irrational exuberance has come to an end as airbnb and hopefully many of these startups that while facilitating many great things also mask an exposure to danger.

I remember when anyone on Craigslist was in the top %5 of nice humans. Of course that is gone now, but airbnb seemed like it was living in the early craigslist bubble.

I am saying those bubbles shouldn't exist. They are naive. And most American humans don't have the street smarts to build their own trust metrics.
