Source Extensions for JSON Feeds

Dave Winer's 'source' extensions add functionality that elevates RSS from a simple protocol for reading posts to a system that lets you consume posts like social media, with user profiles, comments, and likes. I have written about rss.chat before.

Unfortunately, these features are missing from my favorite feed format, JSON Feed. So I took the liberty of documenting a JSON Feed extension that adds them to JSON Feeds. You can find my RFC here. Downread already supports this extension.
