One thing I agree is that hive can evolve into something better. But it's a very open problem.
Let's note that 30:1 vote system allowed for tyranny. Simply, one colluded minority lost to another. Old witnesses would keep around 10 places in the top 20 if not for the 30:1 rule. But before on steam and now on hive this exact rule allowes some of them to keep his/her place as a top witness.
And finally, I do not think that 1 shareable vote per user changes anything. It just scales everything down, no?
Why to introduce and keep such a construct if it changes nothing? It allows a minority to stay in power as long as they cooperate, as I have explained in this post:

P.S. Sorry, maybe I do sound negative and confrontational, it's not my intent.
Best Wishes!
