I really can't believe how much of an arrogant blowhard (pun intended) he is sometimes. 95% of the things coming out of his mouth are negative, cynical, and self aggrandizing. He has some good points, sure, but I really just can't get past his personality.
That was kind of my reaction as well, though perhaps not quite so negative.
It's fine that he has these sorts of opinions. I might have some opinions about this topic, and I might write a blog post or something about it. But I would expect others to tear my arguments apart, because I -- just like Jonathan Blow -- don't really have the expertise or background to properly evaluate something like this.
In reality, though, my opinion would barely be noticed, because I'm just some random person on the internet. Blow is a fairly well-recognized figure, but that doesn't mean we should give greater weight to his opinions on things that are well outside his expertise to evaluate.
