Yeah, in the comment section he does state[1], that you should stick with the one you have decided to pick in the first place.

If you are not using or planning to use sub-domains, the only issue is that you cannot use CNAMEs. This is nearly a non-issue as many DNS providers offer ALIAS/ANAME/ACNAME records that essentially provide CNAMEs on apex-domains.

Chrome messes with the address bar as well.

Safari doesn't mess with my address bar. Chrome on the other hand felt it necessary to remove any instance of www or m anywhere in the domain of the URL before it was rolled back due to backslash. www.m.www.example.www.example.com would show up as example.example.com in Chrome before the rollback.

OP here, minor nitpick: I'm not the author, I just found something interest and posted it.

That said, I agree. The author does jump to conclusions, but that's pretty much why I posted it. It's was first search result and I decided an HN debate would help me find a better answer.

yep he defaults without www.

His non-WWW site is broken. If you manually append the WWW, the site works.

Guess he is Stallmam-serious about practicing what he preaches.

Also this is a stupid clickbait non-issue.
