Understood.
But: when I tell you something, what I say is filtered -- by my (probably not 100% correct) perception of you, by how much time I have to flesh things out, by the specific point I'm trying to make in a specific context (and if I'm running an Amazon Affiliate site, I have a strong motivation to filter in some hardware recommendations that may or may not be necessary). And you don't know what or why I've filtered, so you can't reverse engineer what I've said.
Then when you tell that stuff to the next person, that same filtering goes on, and additionally you probably didn't understand everything 100% (maybe because I didn't explain it clearly; an example is the 'recently been discovered' exchange you and I had up there), so info is lost. Then also you speculate (often reasonably) to fill in some gaps. It is the telephone game, basically; on a large scale it is an echo chamber. That's why I think care sheets (etc) should be written by people with extensive specific experience that is at least largely informed by empirical evidence when possible, and by no one else.
