This is the comment that I made on the original post:

Since limiting the number of votes for witness positions can be workaround by dividing the stake into different accounts wouldn't the better solution simply be to have 1 vest = 1 vote?

For instance, if you have 100 vest and you vote for one witness your vote is worth 100 but if you vote on 2 witnesses each vote is worth only 50. In my view the advantage of using a 1 vest = 1 vote is that the voting potential doesn´t get wasted but by using a system with a set amount of votes you can have alot of voting potential underutilized when stakeholders do not use all of their votes.

I would also add an economic inventive to voting on blockproducers by linking the inflation rewards to it
