Sometimes even the topic is what makes the difference (not even location or device) between talking synchronous or asynchronously. I'm not a very assiduous Facebook user, but at some point I've noticed it can blur the edge between sync/async. Maybe it is not perfect (and maybe it is no longer there), but I think its possible to mix both ideas. Neither should be left out.
