The original point of AS: Main was to provide answers to the most regularly asked questions - to help prevent the tedium of writing the same thing out over and over again. Obviously things have moved on since then, but there are still a lot of people using AS2, and those links are still useful (and of course AS3: Main) - but I never see people using them to help newbs.
Although linking them to the main topic is useful, it's definitely better to grab the URL of the specific tut that deals with their problem - it can be a bit of a trial for new internet users finding the one they need.
In terms of specific AS questions that aren't covered by the AS: Main threads, I personally actually quite enjoy spending 10 minutes solving problems with users' flas or code, I just wish I had more time to dedicate doing it because it can actually prompt me to try things I haven't.
Myself, I learnt partly by copying (from web samples or decompiling), understanding and adapting other Flashers' codes, and while I'm aware there are some who won't even attempt to understand why the code they copied from the internet won't work, it certainly shouldn't be looked down on as much as it is as a way for users to learn.
In general, new Flash users should be treated with tolerance rather than hostility. So they tried to create a game by copying someone else's work... who cares? If they want their game to be unique, they're going to have to learn how to understand AS. There is no place on the Flash forum for the virtual bullying and insulting I've seen in some instances, more often than not by posters who don't have a clue themselves.
The Flash forum is here for the experienced users to help the less experienced, whether it be in the artistic or the coding side of the program. We were all newbs once, some people would do well to remember that and chill out on the abuse. If you think you might have an answer to a question, then post... if you're just going to flame, be aggressive, or give bad guidance... don't bother.
