To actually answer your question, probably the best solution would be a full in-place "update" event as a separate kind with an `e` tag pointing to the original "create" note. This way you you don't have to trace a chain of diffs, just look at the timestamp, and you get verb semantics. This would only be a problem if a blog post had a million revisions, like if a client spammed a live draft as revisions. 5-10 revisions is a lot for a blog post, and easy to process.

I do still think there's a place for "annotations" that clients can display in a privileged position (the use case being  updates at the bottom of a blog post, corrections, etc). Diffs are way more complex, and dependent on each other, but also probably unnecessary for blog posts.
