@smallcircles @steve Could you explain a problem for JSON-only folks? I think the main problem I'd see is if publishers use namespaced terms when they're not necessary -- like `https://www.w3.org/ns/activitystreams#Like` or `as:Like` instead of plain old `Like`. And the Postel principle (sorry Steve!) would say, don't do that, publishers. (And, also, be better prepared for that, consumers!)
