@evan @julian @silverpill @trwnh @mikedev "context" isn't good enough to identify any relationship; this is the fundamental problem. It is a property that should never have existed. Today it identifies one relationship: the (loosely defined) thread. I would argue that this is in fact "common interoperability". I would also argue that this fully meets the incredibly vague letter of the ActivityStreams specification.

I have yet to see an alternative use of context that would not be better served by inventing a more specific term. Yes, this applies to use of context for thread too, but we have 7 years of its user to identify the thread as a defacto standard.
