Why so condescending? Reading your comment, after reading both of the author's posts on his methodology, I take that his approach might not be everybody's, but I took a lot more from his writing, then from your writing.
You tell the author, not explicitly but non the less, that his method sucks and he is an idiot for not using "the right" (TM) tools. Using your method is ok - for you. Using his method is ok - for him. His is not more right or less right. Both of you got your work done and your book(s) published.

Well for some it is also the process that counts. And the ability to get stuff done without proprietary software.
On a final note:
Maybe I just misread your tone (at least, it's the internet) - maybe you weren't so a stuck up. Or didn't mean to be.
