Love the idea! It does currently seem that bot owners dont take the responsibility that they should be and its having a pretty big affect - the way I see it that if they dont put the effort in and Steem falls down (if quality of posts being upvoted get worse, and thus people dont join invest) then bot owners are partly to blame.
I agree that whales have to much SP to manually curate properly and should be delegating to those that they trust can curte well - @curie does a fantastic job!
I wish there were more people on Steemit who thought like you! There needs to be a change in mindset where people are thinking about the longterm success of Steemit rather than just what profit they will make in the next week/month - with the whitelist content quality on trendint etc will go up - which will lead to more potential users and investors which will increase the price of Steem - Happy days for everyone :)
SO happy you agree ;-) thanks for inspiring me to write this comment!
