That was a good read. Somewhat sobering, but good nonetheless. I especially liked how he was very good at assessing what responses are worthwhile, and what aren't - his response to somebody bringing up formaldehyde and PG, near the bottom of the page (when I looked). They got a response or two from him, but it quickly became apparent that they were not in the mood to accept new information, but parrot what they (thought they) read, ad infinitum. Stefan smartly disengaged, while this person was happy to argue with others for several posts.
