A billion dollars for a survey website with no clear sustainable competitive advantage?
Spotify seeing a ~3.5 billion valuation in the face of an estimated loss of 40 million for 2012 – owing your existence to an industry that is kicking and screaming into the digital age (and with strong bargaining power and a strong sense of greed)? It's possible – and Spotify is an exciting entry with some clear success, but almost 4 billion in valuation strikes me as bubble territory, at the moment, given all of that...
Just my daily dose of skepticism...
