Yes I upvote comments. But I'm VERY picky about the ones that I vote on. Voting pays. I'm trying to learn how to NOT waste my vote if I can avoid it. I've taken to making comments rather than voting . A vote is NOT a 'like'. (A comment is NOT a post. they're different.)

There is a NEW change in the making. It's not fully implemented yet and for you and I ( krill...very low powr) it will take a while to affect. The short version is that you get five full power votes a day. The more times you vote than that the less they count.

But wait...it gets better.
If, somehow you manage to accumulate thirty dollars of steem power (THE POWER!) you get a slider. A voted adjuster. With the slider you can calibrate the power of your vote. you can vote five times at FULL power...or many more times at reduced power.

Think of it as water pressure coming out of a tank that's slowly being filled by a drip...drip...drip.

the flip side is that if you do NOT vote at all...your tank runeth over, and your steam power is wasted.
