Allen Holub has the balls to abuse and contradict every well known theory, technology and concept. It is good in a sense that you get some new perspective in contrast to the commonly published theory. Holub in his articles and writings has challenged some of the technologies like AJAX , XML which are like the defacto industry standards. Not only this he criticizes the classic compiler book by Aho, ullman sethi (http://www.sdtimes.com/content/article.aspx?ArticleID=29508&page=2) and call it a mistake to be taught in academics. In his book on Design pattern he has critisized Microsoft MFC technology openly to such an extent that now I myself have started thinking otherwise. I am actually enjoying his writings since some of his criticisms are very true and in line with my personal opinion (Only thing is I didn't have the courage to come out openly).
