Atlas Shrugged sale boosted by Alan Greenspan and Amazon exposure

There was a well written article on Forbes this week - paying a a tribute to Ayn Rand 25 years after her death and 50 years after her best selling book 'Atlas Shrugged' was published. And you wonder why I flog this book - see http://www.forbes.com/opinions/2007/09/27/unsolicited-advice-aynrand-oped_meb_0928unsolicited.html. This book is more popular than ever and it sells better than those current best sellers, 50 years later. Its never been out of print. It sells like the Bible, but thats about where the similarity ends. Apart from the link to Alan Greenspan I think Ayn Rand is attracting sales because of Amazon book reviews - people either love her or hate her.
