A agree with @alyssas but I'd add that it is all part of system dynamics. As the user base grows beyond the extreme early adopters, whales, and steemit insiders that have dominated it so far, the results will change, including the behavior and success rate of bots.

@dantheman's proposal here is good in the sense that it tries to take a fresh look at the problem and improve the algorithm overall, rather than being as clearly a knee-jerk reaction to current dynamics as was the earlier proposal to simply remove curation rewards. Still I think there is a lot of value in letting the system grow and seeing how things actually work as it grows, rather than jumping to hasty conclusions.
