I feel this usually comes from folks with Linux background. You see, in BSD world, specially in OpenBSD, there is good and high quality documentation, which the developers put a lot of effort in providing it. I know, since I did it too in the past, that when you're using Linux, you're basically in the dark, so you go to google, and you try your luck.
Everytime you follow a non official documentation, you waste your time and the developer's time, we're not cranky about "calomel" only, we're cranky about people following unofficial documentation, remember, our FAQ and manpages are accurate 99.99% of the time and they are pretty well written and complete. If you can't figure it out by reading the FAQ/manpages: you're either not ready for it, or we have a documentation bug.
