Many thanks for your comments, up-vote and re-steem.
Hopefully the math will show people that short-term gain pales compared to long-term gain, so if they truly are wanting the best possible return on investment, they should choose the long-term option. Also, if the voting (up or down) has the same weight for everyone, I believe it kind of forces everyone to behave. (Voting on resolutions for changes will still use weighted votes based on vests.)
