Many replies here would do well to read, re-read, and re-re-read with an introspective mindset. This is perhaps the best quality material I have seen from pg for quite some time. Its clarity is brilliant and the thing I liked most was the second, and to me unexpected section, full of the reasons haters gonna hate.
I speak only for myself, and this is a throwaway, so nothing personal is at stake. This is a very lucid and precise examination of the fine controls at stake in writing. Their natural tension, the details of qualification. In my opinion, which may be trash, who knows, this will be cited for years to come because it is, in fact, true.
