@daniel @evanprodromou That's a great question! I think that WordPress downscales its HTML to share with Mastodon and uses a `Note` object instead of an `Article`. I'd love to see better support of `Article` for Mastodon.

In terms of the subset of HTML to use, I don't think we have a definition in the ActivityPub spec. I know that a lot of services and apps scrub HTML sent from a client or from remote servers, but I think the scrubbing process is implementation dependent. I'll open a ticket!
