I'd love to see that. I started doing whatever else is doing is upvote themselves since I only post 1-3 times a day and I spend a lot of time on them. I don't want to wait 30 minutes and remember to come later, so I just click the checkbox (which is defaulted to check but I refused to do it for the first 5 months I was here).
The new change to 15 minutes and the leak to reward pool will change things dramatically. Not 100% sure how I feel about it and if it is the best solution, but I do like the cut from 30 minutes to 15 minutes.
There is a lot of talk about increasing the curation %, and I think this will happen eventually. As it is right now the 25% is more like 16.8% on average.
Curation was 50% at one point in time.
I think that if the rewards more accurately reflected 25% instead of 16.8% like you pointed out- it will be perfectly fine.
However if it is increased more than that- I believe it will even further encourage circle jerking onto just a few posts for pure profit.
