I wonder how many people who are using comments don't need comments. I have seen so many places where comments are enabled but even good comments are not replied to, especially when the post is from 5 years ago.

Also, trying to ensure the correct quality of comments is time-consuming. If someone asks "Why would I use C#?", it might seem low quality and won't be published but what if someone asks "You are using C# but Go would make a lot of this easier", it might warrant publishing and even a reply but how many people really want to start a long discussion with a stranger about the merits of different languages?
