You see to me the problem is that somebody who has a big vote say ten dollars at what Steem is worth right now, and he decides to give a general 20% vote, I really don't believe anyone is going to read over 50 Steemit posts and decide which ones deserve to be voted on, so I think the manual curation idea is really not that very well thought out. By the way I commented after I had read the post and the comments, I actually don't upvote because I have very little SP and I use it just for posts that also tag some SE tribes as I do have some decent VP in some of them.
