So I got in-stream reply contexts showing — perhaps summaries of comments next? I like Facebook’s approach of showing the last 4, a total count and a “show me more” button, which could be implemented simply as a link to the note page initially.

Reply context stream example:

Still TODO: make the ↪ a link to the in-replied-to page, add the datetime to the title for that link, remove the in-reply-to info from the bottom of in-stream notes as it’s noise now
