I feel like this kind of proposals (or the abit experiment) are workarounds that can't really fix the reward distribution.
Some of the more rewarded posts are simple copy/paste of price graphs, or news re-written with other words, while there's a sea of undervalued and original content. I can explain this only with bots + curation rules, but I could be wrong.
Of course a workaround is better than nothing, so, thank you for your inputs.
