You might try discusscooking.com. It's a general food site that has a whole bunch of different forums, including one for cookware. I noticed that one of the recent threads here was also posted on discuss...I think it was about cookbooks.

I am a registered user, although I do have some reservations about its management. But that's probably irrelevant. It is an incredibly popular site, unlike so many others where you can barely find recent posts.

Here is a link that might be useful: discuss cooking
