On: What I've Earned (And Learned) From Writing a Ruby...

- "That’s why most tech books seem to either be by authors who’ve written one book or many books."

All books are written by people who have written (1) book or many books.

Except, of course, those books which are written by people who have written a couple (2) books or a few (3) books.

An interesting semantic snafu! I've changed it to "a single book" rather than "one book." Since, yes, anyone who's written, say 10 books has written "1 book," "2 books," and so on - technically speaking ;-)

Made sense to me. I got that "previously" was implied. You meant those who weren't first-time authors.
