I agree that the curating bots are not good in the level of sophistication they are now, and that there are too many posts for individuals to handle. Do you think the solution I am proposing will help?

I do think that allowing users to choose how much voting power to use is a good thing though. If you have a user like ned where a full upvote will give hundreds of dollars, he would have a difficult time upvoting content that he liked but not enough to reward hundreds of dollars to. Without the option to scale his vote, it would be a choice between giving the author nothing or hundreds of dollars. Authors would either get way overcompensated (taking rewards out of the reward pool that could go to other more deserving authors), or not compensated at all. The weighted vote allows a middle ground of voting to give some money, without giving too much.
