Hi, re #15, it isn't the drop in rewards but the increase in number of votes at near 100% power that is the issue. recently @timcliff wrote a good article (and he commented above too) showing that people can still vote as they please but end up operating at a lower average voting power. Strikes me as a perception problem now - we can juggle the percentage drop per vote and the rshares generated so as to produce the same overall rewards in dollars. I am ready to concede #15 if more people understand that they do not need to operate near 100% in order to be effective voters and commenters.

Re #9, yes, you're right. I expanded upon this in this recent article: https://steemit.com/steemit-help/@rycharde/predator-prey-equations-and-the-steemit-ecosystem

Thanks for your comments. upvoted comment.
