To improve oembed handling, I'm using an experimental microformat property e-x-embed. Some problems with appending oembed to e-content are: * links in the oembed may trigger unwanted webmentions * editing or generating a reply context of the post includes the oembed (poor semantics) * impossible to re-generate oembed later As an example of the last issue, I began wrapping youtube and soundcloud players in bootstrap's embed-responsive class to force them to scale on mobile. This only affected new posts though. With e-x-embed, it will be possible to regenerate oembeds if the layout needs to be changed again.
