I especially enjoy these types of posts. Your posts are so often densely packed with information that I find myself getting overloaded. This format allows for a back and forth between ideas, covering possible arguments, and the mock discussion allows me to take a mental break every few sentences. The end result is a post that I can enjoy from beginning to end, and feel that I've learned a point well enough to argue it on my own.
I enjoy the non-mathy posts. I believe Overcoming Bias is a worthy endeavor, and as a relatively new field of study, the math-oriented posts are important. They are often the most succinct and accurate way to convey concepts. With that said, I find that math posts to be dense with information, perhaps overly so. I find myself unconsciously starting to skim instead of read, and I find it difficult to force myself to pay attention.
The mathy posts appeal to people who are serious about moving this burgeoning field forward, and the non-mathy posts appeal to people who are more casually interested in the concepts, and allow you to have a wider audience. You will have a balance between the two no matter what you attempt, the only question is what your intended audience is, and the best way to reach those people.
