It is nice to see other thoughts on the depreciation of/decay of votes. My two cents on that I mentioned in a dragosroua post:

Depreciated witness voting. Limit the number of positions allowed to be voted for, go from 30 to 15. Your first vote you get to use all your SP/Vest for that person, your second 80% of 80% of your SP/Vest, and so-on down to the last 20% where it then drops by 2% for the remainder of your votes.

This still aligns with the DpoS people, but merges in a semi mutated one vote system.

I have mentioned this or something similar a few times, and most often get the reply it won't work because they will just create more accounts. I am glad that more and more people are making suggestions on how to Fix the DPoS witness vote and still keep it as a DPoS system. If the peole/users of steem block change have the will they will find the way.
