It appears that the deleted post disappears but the child posts don't. That's fine, but the navigation's broken. I can see your post which is a child of the now deleted one, http://news.ycombinator.com/item?id=27969 , and if I follow the parent link I get "no such item", fair enough, but the rest of the furniture should still be there so I can go to the delete post's parent. Otherwise, I can't find out what initial thread this was all attached to. Or can only root posts be deleted? If so, that needs to be clearer.
Really, I don't think delete should delete everything. The username, date, and parent at least should still all be present.
I can't get this to work. I tried to delete this comment: http://news.ycombinator.com/item?id=17545 because it includes my email address. But, I don't see any link for deleting it.
I suspect, like edit, you can only delete relatively new things. Otherwise, users get narked one day and go around and delete all the posts they ever made, to the detriment of the whole.
