cdb,
What you are talking about is indeed an opinion. And everyone is entitled to theirs.
The two Petzal comments were in response to reader questions and were thus advice. Advice is very different than an opinion, and if the person is not qualified to give it, they should not. (Although if that truly were the case, the 'fire would be much less active.)
Now I'm not saying I think Petzal is unqualified to be writing. I'm not saying that by a long shot. As I initially wrote, I enjoy reading his columns. However, after reading those two pieces, I started to wonder if he was stretching things just a wee bit and posted my thoughts up to see what everyone else said, guessing that a few probably know Petzal personally and could offer up their thoughts as well.
