I think he is a saying there could be a hi-bred approach like stake weighted voting at the level of Witnesses and Management.
Without allowing those with huge amounts of stake to control the content.
While I don't think that will ever happen with Steem, some of the SMT and community sites might take that approach. I happen to agree that our distibution combined with DPOS is a huge problem with wisdom of the crowd type curation, there is no crowd. There are a handful of account that can take something to the top of the curve or knock them out of visibility and they don't represent a middle line.
Agreed though, it is unlikely to happen, I don't mind that it gets brought up because there are ways to mitigate our distribution issues, even if we don't choose to implement them.
In fact although Palnet's distribution is still wanky, they at least don't have nearly the distribution problems Steem does and while it is still imperfect, it feel it has a better chance of succeeding than Steem based content sites.
