Wouldn't it be an interesting thing if you could "Recharge" your voting with money. Oops, used all my voting power, enter my credit card here to recharge. (many games offer the ability to buy additional lives for those who have time to engage more. ;)
More pennies to put in the Space Invaders arcade machine! Yeah, I'd love that!!
I think when you power up it increases your votinig power proportional to the new steem power
