Amazingly, the New York Times published a fairly reasonable article on Ayn Rand’s influence on business leaders today: Ayn Rand’s Literature of Capitalism by Harriet Rubin.
If you’re looking to jump into the fray of discussions, you might try the Volokh Conspiracy and the Technorati Trackbacks. (For some reasons, the Google Blog search is completely useless these days. It returns a single link to the article, while Technorati lists 105 trackbacks. Phooey!)
