Maybe that makes more sense :)

Ok, so it is basically a curve that will somewhat limit reward pool payout while keeping an acceptably stable growth curve compared to what is now just kinda paying out like crazy and depleting the pool quicker? While also keeping the payout desirable, if I'm seeing this right.

Let me know how close I'm getting. lol

Actually, I guess I should have asked which one we are using now so I knew what I was looking at here.

So steemit.com is cutting off the graph, but basically:

If n is the number of Steem Power you vote with (simplified), then say you have 100 and someone else has 1000.

N:
100 = 100.
1000 = 1000.

N log N (with log base 10)
100 * log(100) = 100 * 2 = 200
1000 * log(1000) = 1000 * 3 = 3000

N^2 = N* N:
100 * 100 = 10000
1000 * 1000 = 1000000

So a n^2 curve favors the rich, an n curve favors everyone, n log n favors the rich, but not by much.
