Art and Comments
"If you are publishing a post explaining an idea or presenting some observations, it is a good idea to specially treat the comments section.
If the post is public, anybody can land on the page in someway. More readership is a good thing but the readers might not get what you are saying in the depth you were. Your post is a result of days, weeks, months or even years and it's possible that it won't make 100% sense to a person, in just one go. That reader might not have the background-info or know the things you might have taken for granted.
This would create communication gaps and if it's disturbing enough, the reader will venture out to comment. That comment would most probably be edgy & closed-off. You could publish the comment and reply to it, clarifying things. But here again, there is the potential threat of mismatching background. You are replying with info/knowledge you have gained over a period of time to a comment which the commentor made as a spontaneous response to not having gotten your post fully.
This could go on.
Yes, people who know things telling/explaining them to those who don't is a primary way of learning and there is nothing wrong with this or with the discussions/debates that might arise in the process.
But you should consider whether to stage those individual correspondences/conversations publically, right below the original post, visible to a third or fifty-seventh person who will be having their own incompatibility aspects. (You could use plain-old email as the alternative. Also if some relevant points come up in a conversation with someone you have the option to edit the post and add addendums.)
You need to be sure that you aren't making the post page an answer paper full of questions and notes that doesn't really have much connections with your original post.
You need to be sure that someone who would've understood what you said and wanted to go to a higher level with you, wouldn't feel discomfort with the type of comments and conversations that lie below the post."
P.S. This doesn't really apply to the news and press-release niche, most often called as the mainstream media.
