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.
