In reply to Matt.

From sites I've read, it seems like that happens anyways. Even here at the Tavern, someone will read a little bit of the post and then leave a comment asking why this or that wasn't mentioned to which I point out that I did further down into the article.

I too would like to see how this system would work on a very popular news site. I think it would make it easier to see which points or subjects within the post cause the most discussion.
