I have noticed this too, people just arguing with no ground to stand on, making no sense, and not taking advice given, long rants about technology they don't know the first thing about..
I give advice about the equipment I have heard and or own, I don't know a lot about the technical measurement side of it so I look and listen when it comes to that stuff, but when you have people that do know arguing with people that think they do, it just leads to 60 page topics with no point that will never end...
