I guess whoever creates the list can argue that each individual item is sourced, even though the selection of items and their organisation is original research [0], and thus should not be allowed.

I personally think that this list is really interesting and does in fact advance the state of human knowledge. The fact that it's currently at the top of HN and has garnered comment interest shows that you're probably in the minority in your disagreement.
If you feel strongly that this list is trivial, poorly organized, or simply "awful" you're absolutely free to join the discussion and contribute edits at Wikipedia.
