e.g., im reading this book right now (well not this instant but this afternoon)
i started by having to skip 10% of it which is pure introduction and fluff
i have yet to get to the meat of the book-- how to build an earthen floor
by the time i'm done reading and taking notes it will probably be reduced to less than 10 pages
but publishers must justify the cost and need 200 pages for 3 ideas
the world needs more pamphlets
