FIrst off, interesting concepts, your ideas are great! The quick breakdown of the new and old curation rewards was very helpful. I would like to chime in on Potential Issue #3.
I don't think at this time (or maybe even ever) should we be rewarded for downvoting anything. This is a site where your opinion is relevant and can earn you money by expressing such in the form of an Upvote, a positive way of expressing your like in something as well as paying for the curators time.
however, I feel the downvoting system is someone else's irrelevant opinion and shouldn't be granted money/Steem Power etc, ever. The downvoting system is only used by me when I find plagiarism, or photo shop crap, or BOTS. MAINLY BOTS. Or just someone being a complete tool (troll) All of which are definitely not worthy of a curation award by downvoting.
Of course this is just my opinion and I'd love to hear yours and the rest of the Steemit world's thoughts on this.
Thank you for the write.
