To me, I find it more limiting that child comments are not nested within their parents. For example, implementing a show/hide children feature is annoyingly difficult to do, as is showing trails leading to the parent. IIRC, all HN comments are DOM siblings of each other. I couldn't care less about divs vs tables or spacer images. However, I really feel tree structured data should be encoded as such, especially when the document itself is tree structured. It seems more difficult to do it otherwise. Not that it really matters that much. I have bookmarklets that add nesting and trails, but it was just annoying to make them. I realize I'm an edge case, and overall HN is hardly as impacted by it's markup as it is by the community.
