This is a good point. I don't mind people making mistakes (as long as they learn from them). But the squawkers I could do without. Though admittedly they aren't that good. The so called elitists, you know the ones, the vocal ones. Usually try to hide their own ineptitude by being vocal. They know they're bad. So they try to put the blame and focus on someone else.
You can see them in the forums too. They're the ones who complain the most about newbies in groups. A newbie means that someone new plus their own ineptitude means it might not make for a quick run. They'd prefer to be carried by the silent majority. They get all kinds of crazy when we speak up too.
