There seems to be a lot of confusion on this subject. My understanding is that the comments are to be positive and engaging, like you said. The place for constructive criticism is in feedback. I recently gave a comment on a post. The content was pretty good but there were many grammatical errors and it could have been arranged in a more eye pleasing way, but I was there to comment...not to give feedback. So I commented on the content and asked a question and gave some thoughts of my own on the subject matter. That's what comments are for. If I had felt strongly enough that this person needed feedback, I would have handled it in another way. There is the pm, if you can't figure another way to give feedback. Thank you for your post.

I recently wrote a post on this and think that pretty much everyone should lol because it happens way to often. Thanks for article.

Hello Shlomo, thank you for this blog. It does become confusing until you fully understand the difference between comments and feedback.

Yeah, the saddest thing was when I wrote a post like this, I was told by one of the long time members it was not appreciated, because it was a rant against WA. (when in fact it was constructive)

I am going to make a training about this topic...got half way but the site decide to not save my progress.

Good point! I have noticed that too!
