First of all, wonderful pictures you took! They are intense and you can read a lot in them!
Second, not everybody uses their 10 votes to give 100% to just 10 votes and be drained. I for one, hardly vote 100%. I only do it when I really deeply love the post I read. I vote on 15% most of the time. That way I am able to also vote on the replies I get from my readers and reward them for leaving a reply!
As long as we have a slider and we can pick the % we can vote on there is nothing wrong with voting, 100%, 40 % and even 1%
I do get your frustration though but every vote is a vote, money or not!
