The most impressive thing to me is that this feature exists and yet HN seems to have kept its good ol' fashioned <table>-layout. Obviously, it logically follows that it is perfectly possible to write a script to traverse a hierarchy of nested-<tables>, just as it's possible to recreate the Apollo guidance software in Brainfuck...but it's still impressive nonetheless.
