I was expecting the funny part to be that the human curators have to use bots to be more visible. But I guess, there wasn't that exact punch-line. I totally agree with all you said; I have found many human curators and most of their votes do not bring much change. However, what everyone appreciates is visibility and exposure; which in the long-term are much more powerful than a one-time vote. Most of us do value both, obviously - but the way to look at steemit is long-term building.
