Thousands of servers that are federated together into a few networks. I shouldn't have to explain the benefits of a federated chat service vs a corporate monolith like you're describing. Is "/list" and sorting by members or searching for keywords really not discoverable?

All that aside, parent is right, you're basically re-inventing IRC. A more user-friendly client may be a good idea, but it's something that's really hard to make money on, so it's unlikely anyone would bother working on it.
