@scott the core functionality is the grouping of posts by their topic or shared context. the "trick" is that if it's a collection, it's actually entirely up to the owner to decide what goes in there! i could create a collection, declare it to be a ConversationContainer, but then start adding unrelated posts. actually, as the owner, i get to decide what's related and what's not! maybe i require context to be set. maybe i require inReplyTo. maybe i have some other criteria. ideally, i signal this.
