A few years ago, Stackoverflow bragged about how they hosted their entire infrastructure on a dozen of servers. Today I learn that they are losing $80 million a year? What the hell are they doing with that money?
Then it's a management problem: what were those people hired to do, given that the content is generated and curated by community alone?
Given that the software running StackOverflow has been working for many years without signifiant changes, they could probably have stuck to ten times less employees and generate substantial profit, but eh that doesn't make a good exit valuation…
