This is the case (and it's okay)! Every message (other than PMs) is within a topic thread which is within a stream. This can be structured by having ongoing social threads but users do need to know that they should respond to existing "broad topic ongoing" threads instead of creating a new micro-thread for every message. We structure the Streams into roughly: - company-wide announcements - org streams - team streams - social then within #social you could have ongoing topics like "books", "weekend", "music", etc... You can also restrict stream access as needed (only team members can view the team stream).
