The comments section needs a page level [+] and [-] control. If you hit the [+] then all comments on the page are displayed. If you hit the [-] then only the top level comments are displayed. You are then free to drill down into (or collapse) any comment thread independently. This is a shortcut from having to scroll down and collapse every thread if you only want to look at direct comments to the article and none of the replies to them.
