Could it be arranged so that as well as "chat with" there could also be a "chat about TOPIC" so that when an Activity requests a list of every Buddy available to chat with, the list will have some Buddies who want to "chat with" and some Buddies who will want to chat about specific things. For example "chat about the history lesson" and "chat about writing poetry" and "chat about music".
