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.
Is ipfs usage growing? Stagnant? No idea… Diatributed serving of content seems great
I never really quite understood IPFS and why it gets used where I see it today. What problem is it solving?
