I do understand your frustration at not getting a simple and locally knowledgeable answer to a narrowly defined question. At other times I have found myself a bit annoyed when it is clear a poster hasn't bothered to read either the original post nor any of the previous replies.
I truly believe there are few who deliberately post off-topic or generic replies just to increase their post count. I simply see a lot of folks who like to hang out and chat. Sometimes personal biases come into play, and replies fall
into well-worn ruts, whatever the topic. But I have found this to be an easy-going forum with fairly relaxed posting standards. Personally, I enjoy it that way.
As to misconceptions, I am completely sure that no one here has ever posted a falsehood, knowing it to be false. On the other hand, I have unintentionally posted incorrect information, believing it to be true. I have humbly and gratefully received correction, both in public and in private. That's how we learn.
