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.
You know, I probably should have looked into this… yeah, this is me lol. I’ve seen floppies and we had an old rotary phone, but I’ve never heard of a beeper. It still sounds weird but at least there’s a reason.
It’s all good. Like I said, no insult at all. There’s no reason why you would ever have encountered a beeper, it’s one of those things that once SMS came around everybody just collectively decided to move on from. Unlike floppies or rotary phones there wasn’t some continued use for it.
