I agree with this to a long extent. But consider this:
When I first started out in photography about nine years ago I had tons of questions and trouble finding answers. A photography instructor I had while taking a class at a local community college was heavily influenced by technical quality of his prints. He got off on processing Agfa APX25 in Rodinal at 1+300 dilutions and then enlarging it to 4x6 feet and probably had wet dreams about the grain quality. My dad was the same way, and for a while those were the only photography teachers I had.
Then one fine day my dear wife told me exactly what I needed to hear: "Your photographs are not very interesting, Thomas!" I failed to understand, because I could show her prints of grain almost as beautiful as that of my teachers...

Since then I've come a little bit along the way of making photographs more interesting and meaningful (at least I hope so).
1. I'm sure there are more people like me around here that are uneducated about the topic, just like I was (I'm not an expert either, but I know a lot more today than I did back then, partly thanks to these forums).
2. I'm sure that some people are in it for the pleasure of messing around with the technical aspect of photography.
3. These forums I feel are geared more towards the technical aspect of photography. If you look at the way the forum headlines are organized, it's all about film, chemistry, emulsion making, camera equipment. Not until toward the bottom of the list is the forum where you can discuss the art form.
But as I said, I largely agree with you that there is too much discussion about what paper/film/chemistry is best, while in fact almost any materials available today can be used to make interesting photographs if one goes out on a limb to find the limit, exceed it, play with it and investigate possibilities just by having fun with it and working hard, and not least - document it.
Amen, brother. Too much endless rambling on this board about chemicals and densitometers, not enough about important stuff like seeing. Let's all quit arguing and make some kick-ass new work.
