I think the very act of up-voting content is not very well explained and therefore new members don't use their votes.

I have seen discussions where people were thinking they were spending their steem power when they vote, even a few post trying to help explain the process that confused voting power with steem power.

I propose a new header with votes last 24 hour and voting power remaining meter or gauge..

Would also like to see that included in the daily payout reports, it's surprising how some of the best rewarded posters here are the least active up-voters :)
