I was really interested in the discussion of how paper validates knowledge. With the advent of blogs and online publishing sites, any information can be passed off as legitimate. In contrast, paper sources are often more legitmate. Most publishers are in the business to make money and they know blatant misrepresentation of facts will get them fewer viewers. (Although some businesses get around this by feeding misinformation to an already voracious audience.) Newspapers have fact-checkers.

I also found interesting their point that shared documents can create a sense of community among an otherwise diverse population. They mention documents like the Declaration of Independence and the Constitution. I never thought about it like that, but it's so true. I would like to point out that legal documents must provide for the well-being of everyone before they can unite everyone. It's the same thing with television shows and music. You can overhear a stranger in the grocery store talking about Desperate Housewives and all of a sudden, you have a new best friend.
