I'm finding it hard to keep my voting power, it's been an issue deciding how to use it since I started having enough for it to be meaningful. I've kind of decided to just vote for everything now! I literally upvote all comments and posts, mine and others, and basically all of my feed. It does drain my voting power, but I just see it as spreading it around.
Whatever we do with our vote everybody wins, the important thing is that we vote. I would like to keep it higher, but maybe I'll just start giving away Steem or SBD directly after a certain point if I really want to help out someone I like. I'm pretty happy as long as I stay a dolphin comfortably, I'm not looking to get any more now.
LOL you keep upvoting all your comments, you will grow bigger.
Personally, I try to keep my VP up, which means sometimes I have to walk away from here. I found that not upvoting my comment (I do upvote my posts) really helps to keep the VP strong. I also adjust it...everyone who comments in one of my posts gets upvote (unless it is something really foolish). However, I try to keep the percentage down to be able to pass it around.
I do upvote posts at a higher percentage since more effort usually went into them.
But as you said, as long as people are voting, especially those without a lot of rep nor SP in their account, that is what is important.
