I opposite to use the `.zz`. Instead, I think this should be assigned as new TLD domain for all people live in any country, because it is a reserved ISO 3166-1 alpha-2 code, and will not be assigned to any country. It's the best convenient TLD for human on the earth.

There is not much to gain from having a new two-letter gTLD instead of existing all-purpose three-letter TLDs (say, `.com`, `.ooo` or `.xyz`). Especially given that every TLD needs a registry, and `.zz` would be a particularly extra-special gTLD that needs a special procedure to select the registry. Better to make it a reserved TLD if it is ever going to be used.

I consider .xyz to be a good TLD for that purpose already, but .zz would be nice too.
