I support this. I opposed the change from 50% to 25% for various reasons including simply rewarding voters more.
I stated at the time (and this can be found in the old #witness slack logs) that after switching from 50/50 to 75/25 (or even more so the 90/10 that was thrown out as a trial balloon at one point), the asymmetry creates a natural incentive to switch it back. That's because going from 25 to 50 doubles curation rewards (and earnings for all of those voting, large and small) while it reduces content rewards by only 33%. The farther you get from 50/50 the more leverage there is in the effectiveness of rewarding that segment of the user base by moving back toward 50/50.
There are other effects from shifting too much of rewards to content, basically none desirable, unless the objective is to attract extremely successful bloggers who need a large paycheck to be interested. For everyone else, extremely large content rewards are basically useless. (Even for successful bloggers, the 50% increase that comes from 50->75 is not a game changer.)
Good post and thank you for the original thought, since you were apparently unaware that the original design worked this way.
