Doesn't it really depend on what we're reading? I generally wouldn't want to skip any words in a fiction novel. I would love to skip words in most self-help books that turn out to be 3 paragraphs of "the point" and 100-200 pages of fluff to get the book on the shelf. Another perfect example is nearly any online recipe with 25 screens of fluff at the top to get to the 1 screen recipe.
