Then 2011, 50 million users 70 employees. Seems fair enough.
Now about 1500 employees. It worked fine and scaled fine with 70 employees so you wonder if hiring the other 1430 was good business. I guess if VCs are throwing money at you you may as well spend it on something. Though that's probably what Yahoo was thinking when it went to 11,700 employees and that didn't play out so well.
