I never upvoted one of my own posts by now. But had some kind of understanding for people doing it. Though I never put real thinking in it. You did. I understand better now. Yes, I think it is okay to upvote own posts. Maybe the point with difference in upvoting comments is the following: upvoting your post... nobody gets hurt. Upvoting a meaningless comment... the thing about that is in your article. And I must say... even when your comment is a good one with valuable thoughts in it... comments to me are like: I want to talk about the content with the creator. Comments are about content and worshipping content to me. Not about earning money. But about community. So there seems to be this invisible border of good behaviour, when it comes to upvoting the own comments. We can feel it and I guess we feel it in the right way. I still won't upvote my posts. My upvote is worth 4 Cents in maximum, I don't need this. XD
Agreed. Comments are about community. When people use them as an easy way to make more money it feels cheap and kind of degrading to the creator of the original post.
