Oh! Mastodon has built-in Atom feeds for each user:
https://SERVERNAME/@USERNAME.atom
For example: https://octodon.social/@blinry.atom
(via @dredmorbius)
@blinry I think the OStatus protocol (on which Mastodon relies) is actually built on these Atom feeds
@alexduf Oh, right! I remember reading about this. Neat side effect! Yay for interoperability!
