I agree. One of the more annoying things about people who talk too much about typography and other design topics is that they get locked into orthodoxies which are barely even opinion and certainly not even fact. The classic example is Helvetica vs Arial. The first thing every designer learns about typography is that Arial is just an ugly copy of Helvetica and is to be avoided, but in fact, the difference between the two is so subtle that it really doesn't matter which you choose in most applications. In fact, when it comes to webpages, the fact that both of these fonts are being displayed on a computer screen means that pixelation will hide most of the differences most of the time so that they will really be equivalent. People who see the difference between the two on a website and decide one is better are falling victim to a kind of placebo effect. My favorite example of this was a blogger who was extolling the advantages of Helvetica over Arial one day and showed two bitmapped renderings of Helvetica and Arial back-to-back. He intended this as proof of the superiority of one over the other, but he got the two samples mixed, and I had to point it out. Two samples, intended to show how one was superior, but he couldn't even tell the difference between the two.
