I use the comments section to watch for new comments on article that is generating an interesting discussion. It's useful if you already know which article you want to follow (you can scan for the title). I find it easier than revisiting the article's page because comments move around over time which makes it difficult to pick out the new ones. Also, as someone pointed out already, you can find comments that have been upvoted which usually lead to an interesting discussion.
