This is certainly an interesting opinion on matters large and small. Especially as uttered by a global moderator.
I have always thought that longer serving members of a community owe a special care to folks to be more polite than most. After all, they set the tone.
Being rude to newcomers is a great way of reducing a place to a rump of insiders.
Then again, as another newcomer, I may have misunderstood all this stuff.
I have been following this discussion because I wanted to get a feeling for the level of expertise you need. The learning curve is pretty steep. I have been looking for a true "idiot's guide". The FAQ and things are excellent, as is the case by case advice I have seen, but there still isn't something that I can find that matches, say, a Canon camera manual for simplicity. (No jokes please.)
A beginner might be a good person to try this task, but not if they are going to get shouted at by old hands who demand that the level of complexity stay high.
