Agree and disagree. So how does an echo chamber work. Is the first attempt. Which is really how think your thinking.  The point of a positive echo chamber is new ideas grow and hopefully flourish. The Meztdow and CPunks among others, was the opportunity to collaborate in a deformed discussion. Best ideas got to the top with critical thinkers. And that brainstormed. The point of open honest conversation is to agree on the smartest ideas. That’s it.
