Free will never be a price worth paying.
People want to eat but they don’t want to join the hunt. Newspapers, TV, etc FEED people without them having to get off their butts to get news. Blogs, Internet, etc. require they do something to get news (hunt)
Godin states: “In a world of free, everyone can play.” Just because they can, doesn’t mean they will.
My money is on sloth. Nobody ever went broke betting on sloth. A book review on Amazon may be easier to find, but so are 1,000 opinions on it from readers, all of which are essentially crap. A really good book review in the WSJ or the NYT is reliable and usually done by someone who has the critical eye and the command of language that makes the review worth paying attention to. “I really like this book” is meaningless drivel as are the videos Chris Brogan puts out on book reviews; but they are free! (BTW, I care about what Brogan says about Social Media, but he does not deliver a credible book review. I trust this guy with his hefty English degree more!)
