Thanks, pasbesoin, for the frank feedback. You're right that I haven't been much involved in the book program for years. But even if I were, my own technical skills are now rusty enough that I'm not sure my involvement would help. It's ironic, perhaps, that we are now relying more on outside technical reviewers than on the expertise of our editors. And perhaps that is the problem. Our editors definitely used to be the beta users of the book.

The folks who do manage the program now will definitely be taking this thread seriously, though.

Specific criticisms are always helpful, btw.
