You may count me as one of the very few then I guess:
there will be very few who do not give away their votes.
The only real downside to the vote issue are bots, and people that, (like in the real world), just do not vote on anything.
And then there are the people that whine that your vote, or their vote is only worth $0.001, I wish those people who do whine would just send me that .001 vote, I appreciate them. My vote at one time was only that, now I am at the $0.010 range. Moving up. Soon I will get to that magic number of 480 steem and get a slider so I can vote more.
No incentive is worth giving away your vote. People need to stop viewing Steemit as a carbon copy of life. Where they feel their vote is meaningless in the real world, for me on steemit their vote means a lot to me whether it is big, medium, small, or petite, they are all equally appreciated.
