I read it all, consider it all, and then compare it to my own experience. Every brew I do, I either incorporate what I've read--much of it from this forum--or heard with what I know from my own experience.
With that said, I can't try everything, since I only brew one or two times a month, so I find the things that I read, whether it is old--I read Charlie Papazian for years--or the newest Brulosopher experiment, or the latest post I read of Denny or Martin, food for thought or possibly the impetus to change the way I do things.
I guess what I'm saying is that I have an open mind. It has served me well in the sense that I, my wife, and my friends love my beer. That and the relaxation I get from the hobby and the validation that I get from producing something that improves/enhances my immediate society reinforces many of the ideas of the homebrew community on the whole.
Being on this forum, I am a man among giants. So, I say keep it coming: triangle tests, educated opinions, empirical evidence, even anecdotal evidence. I'll run it up the flagpole, see how it looks and maybe even try it myself. But, above all, keep it coming!
