Well what would you consider to be true consensus? 1 vote 1 count (the democratic way) isn't going to work either under the current circumstances, since some people have multiple accounts.
And the whole DPOS idea is, that if you have more to lose, you will usually be inclined to opt for the things that positively impact the community more than the ones that are not so much "vested".
While rep is gamable, delivered just like financial rewards and can be bought, it is far less fungible, as it isn't tranferrable as is Steem or SBD. That means hordes of bots won't have the rep to Sybil attack the witnesses with if witness votes are based on rep-weighted votes--unlike the current system which requires only money to control the platform.
While the DPOS idea is sound as far as you take it in the above comment, clearly ROI based on circlejerks, delegation, and bots severely compromises it's ability to influence whales to act so as to benefit the platform as a whole.
The trending page is a view into how DPOS is encouraging good content. A better view is to examine how Steem is increasingly concentrated in accounts that have more of it.
DPOS is the best way to encourage profiteering, not content creation.
Too bad I can't resteem a comment.
I'm not even looking for consensus on post votes, but there should be a better way for us to weigh in on the platform and how it's run.
