I couldn't disagree with you more. Sure there are occasional responses that might be a different technique. And occasionaly a response is not correct. BUT WE ARE HUMAN! I think this site is ABSOLUTELY GREAT! As much as I have horsed with Hs, I still pick up interesting tips.
This beats the pre-internet days when you couldn't get information in a timely matter while working on your tractor. Relying on a farm neighbor only usually spelled trouble for me. I would end up breaking something worse than what it was. Like the time my neighbor said, "sure you can pull that bull cage straight out". Uh huh.
Try ATIS. You will find that not every response is correct over there also.
