I think of technical discussion and gear recommendations as being, ideally, a fun and positive exchange of ideas and suggestions. It's unfortunate when things should turn unpleasant, or when someone else's ideas are dismissed.
Personally I to see insight into the tools and working methods of some of the more experience forum members -- Paul, APK, Loren, Forrest, and many others. Rather than being frustrated or annoyed when one of them does something in a different way from how I have always done it, instead of thinking "Why do they do it like that? Everybody knows it's better to do it like THIS!" -- I think to myself, "That's interesting. It's different from how I work, so what can I learn from it?"
Many of the instruments, recording devices, effects, pieces of computer hardware and software that I use, I can remember back to when I first heard a friend or fellow recording artist or engineer mention it, or show it to me.
The only negative aspect to discussions like this should be that occasionally, they inspire "gear lust" and make us spend money on equipment we might not otherwise buy!
Well, it could have turned out a lot worse. Yeah, Immersion was a bit elitist here but I don't think he was being malicious. I've seen much worse on other forums, usually about more polarizing topics though.
If this is the nastiest and most vicious discussion to ever happen here, this forum is in great shape.
