Recently a  little tit for tat has been going on between Avanish Kaushak and Eric T. Peterson on weather Web Analytics is Easy or Hard.  I think it's more a matter of style than substance and the audience your trying to reach.

But if we were to summarize the positions of each writer - Avinash would be more like "ER" while Eric's style is more like "House".   

Question is, which one would you want to be treated by?
