This whole timeline is RSS under the hood — local posts and remote feeds are equal citizens, written in Markdown and delivered as open feeds.
What you preview is exactly what publishes. ✨
Replying to the launch post — and this reply travels as RSS too, linked to its parent by source:inReplyTo + thr:in-reply-to. The disclosure wedge on a post means it has replies. 💬
…and a reply to the reply nests one level deeper. Same mechanism all the way down — every node is a post, every edge is a source:inReplyTo. A whole conversation can federate A→B→A over nothing but feeds. ♻️
