The topical relay model is a different workflow:

1. You decided to write about a topic.

2. You client determines that the topic is "sourdough bread baking".

3. Your client writes the event to the "bread baking" relay and adds "sourdough" as a tag.

4. Everyone in the sourdough community forum immediately sees your event. Nobody else sees your event. The moderator (human or AI) can immediately moderate the event, as they know what a sourdough forum event should look like and they oversee the content on that relay.

5. You open your "notifications/chat/kind01" client and can see the responses from the sourdough forum in it.

6. You can respond there, only to them, but you can also allow your wider fren group to see the discussion, by broadcasting it to more relays.
