In essence, this moving conversations from a “category” ontology (mutually exclusive, collectively exhaustive) to a “tags” ontology. In a sense this is rediscovering email/list addresses with cc ;-)

One can set up “tag subscriptions” (propagating hooks) for tags, such that at the lowest level, the messages you see are all the messages you’ve been tagged in. This can even be made declarative, so adding/removing tags can re-jig who will see which conversations.

There is an obvious niceness to this approach :-) What would you say are the problems/challenges with this modeling of the domain?
