Stackoverflow, Snobs and Elitism

I will try to compare this to the situation on GBAtemp. To be clear: Overall this forum is very good! The following lines look way too negative and don't represent GBAtemp as a whole – but it is worth noting some room for improvement.

Code gets picked apart without meaningful insights to take home
We have analogue things here as well. Flat answers, one-liners and replies not helping at all. "How to do X?" → "Do Y instead." → "I don't want Y because […]. How do I do X" → "Lol. Y is better."
The prime example for this is asking for help for a 3DS mode flashcart. So many useless and intolerant answers that simply do not help – combined with calling the OP of a thread stupid in a roundabout way.

Just answer your question yourself
Rather than getting no answer at all… there is another possibility: Instead of staying friendly and trying to find out what is happening… why not just borderlining an insult and use Google as a verb (and reducing search engines to just one provider)? I've seen that here as well and I don't like it.
The least creative approach in this regard is lmgtfy. Somebody asks for help… and gets their own question thrown into a search engine. Strictly speaking many things can be found online – when knowing the answer or at least the correct search terms. As good for your personal education research may be, it can be hard, tedious and useless… and come near re-inventing the wheel: If you know the answer to a question it is faster and easier for a help seeking person to simply give the answer than pointing to the market leader in search engines.

A real shame, when the original mission is "help"
I have to say I was often near of asking noob questions here on GBAtemp about topics I don't know well (like Android) after searching a lot and not being able to achieve my goal. I'm sure somebody could have easily answered them. Fearing lmgtfy or a link to xda-developers, I refrained from doing so. From my >2500 posts… I guess less than 10 are questions for my own affairs.

Downvoting, blocking, ignoring…
My stance on this can be summarized in a tiny picture:
Preventing any discussion, suppressing any deviating opinions; it is so easy, convenient and widely used on the internet. In the case of stackoverflow: If you already have to be an expert to be allowed to participate on something, there can't be any new beginners.
==================

The best thing to counter this is staying friendly yourself. Trying to help when you can and maybe even telling people to stop using lmgtfy. If one has no intention to help and cannot post in a constructive manner, they should not post at all.

If a site like stackoverflow is so snob/elite that they don't want anybody new… well better not frequent it.

"hey guys how do i do this"
"you absolute fucking babbon, you worthless idiot, this question was already asked in 2007, not that you would even know what years are, you fucking oblivous moron, how do you even live being that dumb"
