With apparently 5 mn users, Microsoft just paid ~$200 per user... C.R.A.Z.Y. This just beat Instagram to a pulp as the yard stick for ridiculous valuation. When do I see an Oatmeal comic on this?
Yammer charges $5-$15 per user per month. if everyone of the corporate users were charged $5 per month its $60 a user per year. How does that compare at all to a company which had no revenue?
