I'm completely against having a separate rewards pool - especially if it's at the expense of current post/curation rewards. I think it will just encourage more comment spam and abuse/gaming of the rewards. If this actually becomes a thing, the rewards pool should be small and it should not come at the expense of curation. With curation being only 25% as it is, a 38% haircut would make holding SP damn near pointless, which then makes the entire three-token system, including inflation and interest, pretty much moot.

Agree, curation rewards is the main reason people buy steem power, they should increase not decrease.

I'm in favor of keeping 24/h payouts. Instant gratification is everything.

This is my proposal for comment rewards

How about allocating a percentage of author rewards to commenters in that post, authors could chose how much they are willing to give..which means new authors could decide to give a higher percentage and so they would get more comment/attention to their posts.
I think it would be easier to use the same pool but allow authors to give a percentage of their earning to commenters.The idea that authors can chose the percentage they give to commenters or even curators is a very interesting idea to me because it gives authors new ways to get noticed. Today there are 2 ways authors can try to boost their article, by promoting it or by doing a 100% steem power post. If authors could also chose to give a certain percentage to commenters/curators then new authors could decide to give 100% back to commenters to get more attention. There are also many authors who actually prefer attention than money on some specific posts so they could also chose to give a high percentage to commenters.
