1) I disagree; chat rooms, forum threads, comments sections, etc. are all just different presentations of the same generic data structure (objects in collections). I could pull the AS2 data for this entire chain of replies and render it as a chat room, or as a messenger, or however I wanted to -- flat chronological list or otherwise.
2) I would use `Group` to represent an actual group of agents. For a group of posts, I would use Collection.
