pbreit has a point. Dismissing something as a "turkey" after just one day is unduly harsh, and to call that "bringing up critical viewpoints" is euphemistic.
If that were the only comment the author made, sure. He did a pretty good job of defending his view, I think, with lots of citations etc. It is a viewpoint -- it's the opposite of looking at something and saying, "ooh, this is new and cool!" Now, it's probably more productive in most circumstances to have an open mind, but that is a matter of preference. Personally, I like to have my childlike enthusiasm for new things balanced out by the voices of other, more cynical people.
