eveything that you've said phil I've seen (and participated in) on other forums with other activities as well, to the point that I'm being called an 'elitist' in other hobbies I'm involved in because I don't go out of my way to inform noobs or teach them skills every time... because I've already taught those same skill building sets with two dozen other people who came after me already, and half of them aren't even around anymore. I think it's part of the growth pattern and experience... and after hearing the same entry-level issues from noobs for the umpteenth time you begin to occasionally spout MTFU.

I don't think there's much wrong with it, so long as you're not just saying that to everyone all the time instead of every once in a while, and so long as as a collective someone is teaching the new people, rather than everyone blowing them off.
