I think there is some value (for the right project) in longer form works that aren't just a series of independent articles. Of course, nothing wrong with publishing excerpts. There's also nothing wrong with writing a shorter book if that fits the subject matter. Just because the economics of the publishing industry tend to force length to 250+ pages doesn't mean you can't do a 75-100 page book on your own.

I'm not sure how important physical books are outside of Amazon at this point.

But YMMV of course. I'm in a situation where my books are about gaining credibility and visibility. The money is very incidental.
