There is a shopping mall called "Metapolis" in Korea.
What do you think it means? I don't get it.
I want to analyze it like "meta = metal" + "polis = city".
And I think the play would have been better if the name had been Megapolis (because it is big, while 'meta' is simply irrelevant). I guess the people who named it thought 'meta' sounded cool because of the HTML tag.
