You say "At this point it's basically equivalent to the author and you pooling your SP." This doesn't sound right - I thought that total voting weight was proportional to the sum of squares of voting accounts' SP; isn't this so that putting all the SP in one account is strictly better than splitting it between accounts? Isn't this a protection against collusion in itself?

I'd be interested in your thoughts on my informal proposal to create a market for curation rewards.
