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.
That XMPP’s extensibility is in itself a strength and a weakness is indeed a valid argument, as you’ve exemplified. I was expecting you’d criticize OMEMO though…
No, it didn’t die off, it’s still used. IRC is still used as well, probably more or less at the same level. But if you define usage as “used in business” well then probably just a few cases, yes.
I hadn’t heard of Cisco Jabber but i’ve heard of Google and Facebook - both companies’ messengers were, initially, based on XMPP but they EEE’d it once they got enough users and walled their gardens, dealing a major blow to the protocol.
Can i fight my inner daemons at least? Please?
