My main concern is that I really strive for consistency across the site, and I am very hesitant to change behavior of a feature for a single area.
In every feature of the site where people can comment on a contribution (making a thread about it) they all behave the same: a list of threads are presented and you click on them to read them. It is this way in the ideas, blogs, database images, etc.
So if I changed the way this was presented, it would completely alter the flow of that feature and I guarantee will confuse some people who get used to how the site navigates. So, to make such a change, I think it would have to be a pretty big reason.
