Dave Winer has an interesting post about RSS and "Facebook Instant Articles" here:

One feed works for both Facebook and for regular RSS readers.
I'm thinking about doing this on one of my ikiwiki sites. Any reasons not to do this on a feed?
If it's a compatible extension to RSS (adds new elements but doesn't require changing much/anything in the existing feed), I don't see why not. I think you'd just need to adapt
templates/rssitem.tmplandtemplates/rsspage.tmpl. Please contribute your changes as a git branch and/or a todo item.If Facebook also supports Atom, I'd prefer to use that instead of RSS - RSS is poorly specified, and the Atom spec fixes a lot of the vagueness.
