Don't know if you read it, but by not upvoting, you'll get no curation rewards, and what's more, your 0.010 self upvote on your own comment won't show up as rewards either, it's too small, and will be dusted away unless it's at least 0.020 at payout time. I just thought you might like to know, the penny self-vote is a wasted vote, when you could use that same vote to curate posts that you want to comment on. To comment without upvoting the post is something that I would never intentionally do, because it's considered to be bad manners. Save your votes for curation and you might see some rewards come in. If you read the post, and still want to comment on it, you might see some rewards that way too.
