I've been trying to get to the heart of Quora and LinkedIn view numbers. My experience is that the absolute value is high but that the value of those people is close to nil. I know I'm not alone, but I don't know if that's a near universal experience.
My anecdotal experience is that I never get retweeets or mail from things I post there, whereas the people who read and then respond on Medium seem like the exact kind of people I want to influence. Not all viewers are created equal.
