I don't care about typos. The note is perfectly sucinct and to the point. It is obvious that what's in this list is more than enough materials to go thorugh in a week long seminar or in a very thick book, and I don't think Bob ever intended this post to be a complete set of instructions.
I do like to see the forms he shapes with his hands (like ass and bill as said above), like in a form of uploaded digital shots. Would you be entertaining questions? Possibly write an instructional book? I'd really would like to see him work in person!
