Another thing to consider carefully: right now the shape of the curation reward curve is related to the author reward curve. Both are initially linear, and around the same point, the author rewards curve up and the curator rewards curve down. If the author reward curve becomes essentially linear, that will change the effect of additional votes on curation rewards. I haven't run the numbers, but I think it would make curation even less profitable for later voters.

So keep that in mind - making author rewards flatter without changing the curation curve will probably load curation rewards more towards early voters, which probably is a pro-bot change.
