On the final question, obscuring and distorting feedback is always bad. You could certainly intermediate a process but do so in a way which maintained the integrity of the feedback loops… but that is rarely referred to as intermediation (though technically I believe it still is).
On the former — thanks for the critical feedback. Seriously! I have been releasing this series as components of a larger Feedback Manifesto. I will give this article a second go over as part of that. Perhaps I missed a bit… getting a case study, a general principle, and developing a critical concept in under 5 minutes has proven challenging. But then that and dialogues like this are why I write in the first place. Thanks for reading! And commenting!
