Julian has added an enormous amount of knowledge to this site in a short period of time, and he has done so in clear, concise and interesting ways.
It's very rare to find someone who does so much original research and hands-on experimentation and is so willing to share his knowledge. His results are not guesswork, but instead involve empirical processes that are so important in advancing real knowledge. And he encourages others to do such research and testing, even if just to challenge his results if they think he's gone astray.
Julian actually does things out in the real world. He shows how he does them. He shares his findings. He encourages others to do the same. A rare man indeed.
And if he sells a few books while doing it, good for him. The books' purchasers get the in-depth knowledge that only detailed books can provide, and those who don't buy the books still get a lot of free information given right here on this site and in the you-tube videos he has made.
Now, could he use more tact in confronting those proffering what he sees as continuing and uncorrected misinformation? Sure he could, and often should. It would make him more effective.
But tactfulness, although usually desirable, sometimes doesn't get the job done, especially if incorrect information is treated with the same gravitas as correct information and keeps on being repeated and often otherwise unchallenged.
It brings to mind several TV documentaries I've seen recently about airplane crashes in which the pilot is doing something wrong that ultimately destroys the plane and its passengers. The copilot, knowing that the pilot is making a mistake, tries to tell the pilot using a polite, tactful approach that fails to get the pilot to recognize the problem. So everybody goes down in the crash.
The copilots were nice, but ineffective.
Had their passengers known what was going on in the cockpit, I doubt they would have applauded the tactfulness being employed up there.
