I take your point. But note that I'm here upvoting and commenting still!
I saw the link to this article in my RSS feed, and I took the time to open a browser, find the link, and comment because RSS adoption is something that I genuinely want to have a conversation about.
Which means that with RSS, you can still be a part of the community, you just won't reflexively upvote or spend time in the comments section.
Comment sections should have their own feed. Just like sub forums, users and search queries. Each comment could have its own feed of replies.
Sometimes an uninteresting website has a very interesting article. This is specially great for supper niche stuff. An empty feed should not draw much attention in a reader. The single comment posted years later could be really useful.
