I self-vote my own posts because sometimes my single vote represents the majority of the value that post will get. I work hard on most of my posts but don't have enough of a following to guarantee a consistent payout.
I will very rarely vote on my own comments. I don't think what I contribute in the comments is worth all that much! Lol. If anyone disagrees, they can feel free to upvote me.
What bothers me more than anything is the selfish voting behaviour of some users. They'll comment on my blog posts but won't leave me an upvote, yet they'll upvote their own comments. I hate that. I hate seeing comments worth more than the post that they're left under.
But you understand the labor theory of value is bogus. Working hard does not equal greater rewards. It's all about building a following, relationships, adding value, etc.
If someone doesn't upvote your post and they do upvote their own comment, is it a positive comment or a negative comment towards your point? I can see people saying, "Hey, look at me, here's why this post is wrong!" and not voting for it. That makes sense to me, and I may have done it myself here and there. That relates to my point above about influence and power.
Yea, I didn't mean to suggest that I agree with the labour theory of value. I know it's BS lol. One of my earliest posts was about that. All I meant by my statement was that I value the work I put into my posts, therefore I want to pay myself at least a little bit.
I'm talking about people who write comments like "great post!" And give themselves ten bucks without giving me anything.
I agree with you about leaving negative comment while not upvoting the post. I've done that. I did it just today when I found that someone had shared my Steemit Voting Power animated instructional video without giving me any credit.
