Thanks. I don't partake in any newsletters and don't really write about languages in general, though I am interested in them. As I said in my parent post, there are ramblings on programming/Lisp/etc on [1]. There are topics related to the above that I plan on writing about, including the somewhat messy state of type/data-driven programming in Lisp, and so on.
