Before HF19 that was my practice. It is naturally how people treat their community, those they follow, and who follow them.
I can't do that anymore, because when I do, my VP will not recharge fully. I already need to not vote for a couple days to recharge it now.
I have never intentionally voted my own comments, prolly because I didn't know about bumping it up until I had only 10 votes to cast per day.
Edit: I would have voted your comment before HF19, but can't now.
