Of course, it also implies that Matz did NOT read the book... :-/

Right. Says nothing about the quality of the book.

Also, I'd like to read the book, but not for the price the author is asking.

I'm impressed that one can sell an e-book for near $1/page, though. I realize that, in the end, it's about value delivered, not page count, but still.

It tells me that people are not as price sensitive to some things as I thought.

That's why it's important to sell more than just an ebook. I included 2 full languages you can use in OSS, http://jashkenas.github.com/coffee-script/ started from the Ruby language included in the package. + screencast and more. Also the book is amazingly good :p

Good points. :)

And a better deal.

Taking advantage of "This is a not a dead tree" is sorely lacking in the E-books I see. Even the page layouts of E-books assume you're using some shaped-like-a-page viewer, rather than allowing for a flexible layout that works well across different screens and devices.

It was a single tweet (http://twitter.com/yukihiro_matz/status/3875573878). A more direct translation is "book I want".

I'm glad the site links to the source, though. I like easy to verify testimonials.

Indeed I thought it was a joke until I read the testimonial.
