Deletion of Verne Harnish

Comment: Looks like someone very successfully weaved his organization and other entrepreneurs together with numerous articles. I am new to voting at AfD so I guess I will pose a question as this one is not obvious to me. Would subject pass  under criterion 3 as his book Mastering the Rockefeller Habits, even though not in many libraries, has been regarded as a go-to source for the business community? http://www.businessinsider.com/verne-harnish-gazelles-roadblocks-2012-11, http://www.inc.com/magazine/20071101/the-art-of-the-huddle.html, http://www.forbes.com/sites/scottallison/2012/08/31/mastering-the-rockefeller-habits-how-to-scale-a-hyper-growth-business/. I agree about the article puffery, but trying to judge the sources before gutting the article down to simply being an author, not the founder of a world-renowned business organization
