Damodoran is known for his value investing analysis. He is an academic, and value investing is the only form of investing proven to work.

However, he does a good job of wearing hats of other types of investors, which is why I enjoy his analyses.

Bottom line is that social media companies will either have to sustain these valuations forever, or they will eventually fail. When times of turmoil hit, user base and engagement will not be enough save a company. Cashflow is the only surefire metric that indicates a company's success.
