Julie and Julia Movie Review

It's been a while since I've done a movie review, but here goes... Julie and Julia is about two women.  Julia Child who writes a cookbook called Mastering the Art of French Cooking and her protege, Julie Powell a woman from Queens Borough, New York City, New York.  Julie decides early on in her story that she will make every recipe in Julia's book in one year and will blog about her adventure.  Her blog was posted on Salon.com  I'm not sure if it's still there.  She turned it into a best-selling book.  Why would she or for that matter, her publisher, want people to be able to access the material for free when they should be paying for it?
