There are a couple I have in mind. Like many techies, I am a huge fan of RSS for content distribution and XMPP for federated communication.
The really niche one I like is S-expressions as a data format and configuration in place of json, yaml, toml, etc.
I am a big fan of Plaintext formats, although I wish markdown had a few more features like tables.
Presumably you could just buy that paper size? They’re pretty similar sizes; printers all support both sizes. I’ve never had an issue printing a US Letter sized PDF (which I assume I have done).
Kind of weird that you guys stick to US Letter when switching would be zero effort. I guess to be fair there aren’t really any practical benefits either.
I’ve literally never even seen A paper in America. Probably would have to special order it from another country
