I'm glad to see that Mr. Parr, at long last, admits the obvious:
Keene's books are of low quality. The only remaining issue is whether
he has some excuse--e.g., there's a market for it. Obviously, Mr. Parr
thinks making a quick buck is more imprtant than making sure one's
books are free of errors.

just state that most of the works written by the
famous GM are hack jobs. Which is nonsense on its face.

Oh really? Let us look at, say, Keene's latest ten books and see what
the critics said about them.

It's true that not all of Keene's books are "instant books", but
unfrotunately one cannot turn off "hacking mode" at will. When one is
used to writing insta-books using inaccurate cut-and-paste methods,
this method of "writing" infects one's non-instant books as well.
