I didn't like the subtitle though: <i>Why Chris Anderson's theory of the digital world might be all wrong</i>.<p>Anderson explains on this blog (<a href="http://www.longtail.com/the_long_tail/2008/06/excellent-hbr-p.html" rel="nofollow">http://www.longtail.com/the_long_tail/2008/06/excellent-hbr-...</a> ) that Elberse uses different definitions for 'tail' and 'head'. So it's all about definitions, rather than having posited wrong claims.<p>The article's author never disproves Anderson's theory. So it's a bold statement to say it <i>might be all wrong</i>.
