This went out a bit faster than I anticipated. But then again, it's nice to see the discussions and feedbacks that it generates, so thus I am happy to see it shared even though I myself would have preferred going over it a few extra times before announcing any stances on such important questions.

Anyways, I am practically "acceptable" towards any new idea that has a decent argument behind it. Steem is still young and we will have to experiment with alternative solutions than the ones that we've got, not only discuss and speculate on their potential(s).

What's more important to me is the approach we take to test whether or not a proposed change has the desired impact that we want. Witnesses, developers, stakeholders, and active community members can discuss all they want which changes could result in better outcomes for Steem (not that there's a clear agreement among all parties of what an "ideal outcome" looks like, but let's leave that for now). In any case, if changes as big as those suggested in this chart (50/50 split on rewards and a new pool for downvotes in particular) are implemented, they better change behaviors in a direction that is desired and produce results that align reasonably well with initial expectations.

To do so, the desired outcome ought to be clearly defined and some measurable outcome that would constitute a "success" or "failure" should be set. Then the whole community can understand why a new change is being tested and join in scrutinizing its effect.
