Great, comprehensively written piece. Nice to see so much info on high authority site ranking factors in one place. Especially like the section on thinly written, or filler, content. I believe in the long term, users ability to share, rate and comment on content (did you find this useful?) can greatly separate the wheat from the chaff. I wonder also how the Google +1 button will effect this.
