After three years here I think the problem that hit Steem was delegations, all of a sudden I saw curation trails, bid bots, guys who were delegated Steem self voting. If delegation didn't happen people would have to vote for their rewards, bid bots would disappear, but this isn't going to happen because it will hurt a lot of people and some of these are big guys. In fact it would hurt me because I make a few cents per post mostly from two places that rely on delegations, Actifit and Busy. but frankly if delegations weren't possible I think it would have the better content receiving more rewards, that of course would leave me screwed with only my 0.003 cent self vote which isn't even dust.
