Would it be crazy to scrap the TLD system altogether and build something better in its place? I'd love to allow for wildcard TLDs, or even remove the dot requirement altogether. Built in unicode support, but with a layer of security to prevent against similar-looking character abuse. I know that very idealistic and probably naive, but the current system just feels very archaic to me. Can't we do better?
