Well, one thing that can be done is to reverse HF19.
All it has done is penalise the power voters - the ones that did the hard yards of curation. I'm not sure how or why the linear voting thing came about, or why they decided to drain people's voting power after 10 votes, but one good thing about steemit is that if an experiment doesn't work out, it can be reversed in the next hard fork.
HF19 has been a mixed blessing, for sure... allegedly, it would make minnows feel like their voice had a "say" because an upvote would be worth 3-4 cents instead of zero. Whereas that has perhaps happened, so much else seems to have gone backwards...
