Ask HN: Technical forums that are not dominated by pedantry?

I'm finding forums like Stack Overflow to be almost unusable due to the sheer number of useless pedantic criticism that people post instead of actually answering questions.

This usually falls into one of the following:

1. Nitpickers who interpreted something in your question as incorrect. They will focus on this minor point that they think you said.

2. Dogmatists who consider what you are asking about as violating some sacred creed, like model-view-controller or following a pattern. They believe that you've violated that, and they are going to focus on that. Nevermind that you're asking about performance problems with some function, they are going to criticize you for using that function.

3. Evangelists who think you should be using newer technology Y instead of technology X. You asked a question about configuring something in X, and instead get lots of useless responses telling you to use Y. It doesn't matter your reasons for using X. X is stupid, use Y.

I suspect that if the voting/karma behaviour of these forums could be changed, there would be less of this.

But are there better forums where this sort of behaviour is discouraged?
