Seeing the same type of threads repeatedly seems more like an indicator of how poor the kit instructions are for beginners. Granted, some people wouldn't ever read the instructions anyway, but if you are packaging and/or selling kits (either equipment or recipe), you've got to know that there is a higher concentration of new brewers
Is it?
I understand your point about happy customers but I occasionally write service bulletins and work instructions. They are not written at the level or with the expectation that someone with zero or very little mechanical knowledge just steps in and does it.
The same holds true, IMO, about beer kit instructions. They are not written with the intent of being the beer brewer's only point of experience and reference.
Saw a point made on another forum where someone suggested to RTFM but was called rude for saying that. The rebuttal to accusation of being rude was, "What's more rude, someone taking no personal responsibility to become educated about what they're doing and instead expects people to spoon feed them answers, or someone who simply suggests they first make an effort try to educate themselves with readily available information?" Thought that was an interesting point to contemplate.
