I've already mentioned before "50/50" initiative started about 2 month ago on Golos, when some authors started to use cahsback-bot with the goal to provide 50/50 author/curarors split.
After one month about 10% of total revard pool were distributed for those posts.
Now, after 2 month, it's more then 30% of TRP already.
So, definetly it's some option people are ready to use.
If you check out my Golos wallet you'll see a lot of transfers mentioning "50/50" in memo.
