SharePoint site news articles are great with the embedded comments section. I would ask and recommend that there be some sort of notifier/alert to the original comment poster when someone else responds to it. This would help keep conversations going forward. It's rather hard to find your original comments when there are many comment posts.

We need the ability to follow pages and get alerts for page and comment changes. The first time you add a comment to a page, it should set the page to Following. You can then unfollow if desired. Subsequent comments would not set Following again.
