I'm always surprised when I start to read a thread and then I realize how many of the participants are retailers. I wonder if this has a deterrent effect on discussions -- not in a nefarious way, but just that open, back-and-forth discussion will lead to criticisms that would be commercially uncomfortable. But surely the main thing crowding out good discussions is just the sheer proportion of members who are uninformed, which is probably the inevitable result of any hobbyist forum being around long enough. I guess if this site had kept commercial interests more in the background, it would have been a good thing, but probably not a saving grace. I think your point resolves an apparent contradiction in what I'm saying: that the site is lacking both enough members with first-hand traditional clothing knowledge and from people who've drunk too deeply from the "first-generation" posters. I value the non-Internet-mediated knowledge more. It's the River Lethe coursing through all of our lives.
