Excellent post, you forget to mention the bots that vote to get the best curation reward, if you look at certain authors you would realize the trend. I did a post on this, are bots healthy for the steemit commuity, I know they do a excellent job, but are we going to far to maximize gains. Check my post out if you get the chance. You would also find out, that a lot of the day to day interaction and traffic are actually "Bots"
