Well here's my forward looking projection - Groupon, Zynga and Pandora will go bankrupt within the next 3 years.
It really isn't that bloody hard to see shit for what it was - if you aren't making any money, if you are buying revenue, and if your service is commodity then you will be both a bad investment and eventually go bankrupt. Enron, WorldCom, MCI, Zynga, Groupon, Pandora fit these cases and hence will fail.
It irritates me saying "Ohh who could've predicted the GFC, or Enron or WorldCom or the DotCom bubble or whatever". Just because you don't see the asteroid coming before it crashes - it does not follow that it was a black swan. Grab a telescope and you'd have seen it coming 30 years out.
If you aren't making money and your business model is neither defensible nor proprietary - you will go out of business.
