Why are the first few comments shown instead of the last? When asking a question (I think, this is my first), but also when answering, I'd like to see the last comments on an answer so I can see immediately if any additional comments are added since the last time I checked. Also, hiding the newest comments might add the risk that they are not noticed at all.
I sometimes see than an answer triggers a discussion, or that additional information is provided. This would be more convenient if the last comments are shown instead of the first.
