Anderson explains on this blog (http://www.longtail.com/the_long_tail/2008/06/excellent-hbr-... ) that Elberse uses different definitions for 'tail' and 'head'. So it's all about definitions, rather than having posited wrong claims.
The article's author never disproves Anderson's theory. So it's a bold statement to say it might be all wrong.
