I agree that I don't like trees, but in HN just go to your user in the upper-right, and click on comments. Problem solved! Still a tree, but no more clutter.

Looking at flat comments for an involved discussion is sometimes confusing because you have to scroll around even more to see who is replying to what.

Maybe PG would provide an option in user config to view comments in a list rather than a tree if we asked.
