My guess is that it stems from the fact that nowdays people are more apt to ask questions before they've even gone over the basics of the language, which can be frustrating to those trying to help out. Back when I started programming, I read several books from cover to cover and practiced quite a bit before I posted even a single question on a message board. As a result, I generally received helpful advice.

>> But I've read some really nasty responses to the extreme beginner questions and I've noticed that this is one of the only scientific fields who's culture is akin to artistic elitism.

I bet if you got on a chemistry message board and asked "what kind of protons are metals made out of?" or such, you'd probably get some pretty ugly reprimands from the respondants, as well.

To be sure, you're always going to encounter trolls and rude people from time to time, but for the most part, at least, you should expect fairly constructive input.
