A huge pet peeve of mine are sites that reject the new TLDs in emails or URLs. I use my hotfresh.pizza email address pretty often and you'd be surprised how many sites reject that with "Please enter a valid email address." Infuriating.

You'd be surprised how many sites reject my domain, 3e.org. Sometimes it's because it begins with a number, sometimes it's because it's too short.

I've had Gogo's inflight wifi not let me sign up because my email account at gmail started with a number.

To be fair, an old RFC referenced by an RFC that is referenced by the current thing specifies that a segment of a domain name can't start with a number. Obviously, that isn't true in the real world.

So, TLDs are selling (technically) invalid domains?

And every major implementation supports them.

Well, I trudged through the RFCs in ~2010, so it's possible that it's been updated since then.

Same issue with our hi.fi. Facebook's JavaScript SDK wouldn't write cookies to it, instead rejecting it as too short and invalid. Had to open a ticket and the oversight was corrected, with lots of embarrassment and apologizing.

There's also a proposal in front of ICANN to allow dotless domains, eg http://pizza

Ha, and HN is on board, apparently!

So to conflict with Intranet sites? Bad idea in my opinion. I already use lots of one word Intranet sites at work. If http://pizza were public you'd have to have some way to distinguish between the local site and the external. That also seems like something you could then spoof.

There's no money in intranet addresses.

This is why I haven't been able to update my Yahoo account in several years. I keep sending them bugs about it, but no one has fixed it yet.

Sometimes this isn't the website, it's actually the third-party API their using for users/signups/mailings/whatever :)

Little off topic but what inspired that domain?

Simply my love for pizza, especially the hot and fresh variety. When I discovered the .pizza TLD, my eyes lit up.
