Well I think a concerted marketing campaign would have solved that churn problem by insuring there were more joining than leaving. Facebook has millions of people leaving it each day, however it has tens of millions joining.

My worry is that Steemit HQ have no idea about marketing and/or do not think it's important. They have this misty eyed view that everything will happen organically when it won't. Marketing Steemit is hard now; as it's very hard to get people who aren't into crypto excited at potential rewards of pennies, however it is not impossible. Though it must be tried to be achieved.
