Too Many Non-Readers

Marc's "Advice for Authors" post pointed me to Seth Godin's "Advice for Authors", which in turn pointed me to the following stats from Para Publishing:

<> 58% of the US adult population never reads another book after high school.

<> 42% of college graduates never read another book.

<> 80% of US families did not buy or read a book last year.

I find that terrifying. I have a wishlist on Amazon with over $1,000 worth of books I want to read. I have no storage in my Manhattan apartment, in part because every nook and cranny is filled with books, books, books. I spend my commute on the subway reading books. I'm going on vacation later this month, and I'm excited to have more time to read books.

Who are these people that don't read? What's wrong with them? (And are they asking the same thing about me?)
