I don't disagree with you. I would say, though, that unlike some other sites that have severely restricted fact-based, scientific discussion (<cough>AudiophileStyle</cough>), the Hoffman forums are primarily about music and secondarily about gear, which is sort of the converse of most hi-fi sites.
Again, not defending or excusing their silly rule, and agree 100% that the woo-woo that goes on there is not good for people becoming properly informed. But there is actually a good deal of latitude when it comes to being able to say that power cables, interconnects, cable lifters, green markers, and so on are BS and don't do anything - the rule is narrowly written (and in general fairly narrowly enforced) to cover explicit debates about blind testing vs subjective listening.
Personally I don't find the silliness about gear and the science of sound reproduction to be the biggest problem there, as there are plenty of folks there who agree with us (at least generally). What I find the most problematic are the folks active in some of the really huge and popular CD music threads who consistently claim that certain CD pressings sound better than others when the digital data on the discs is identical (in other words, bit-for-bit identical digital production master but pressed at a multiple plants). Those folks can be challenged in certain threads, but there are others where they are allowed to basically say whatever they want. The "best-sounding" of these identical-in-reality pressings are of course almost always claimed to be the earliest pressing, or the rare and expensive Japanese pressing, and so on. To my eyes those discussions take on more of an uncontested religious-type feel than the discussions about gear and hardware.
At any rate, I personally have found a lot of value in the Hoffman forums, in the areas of discovering new music (or discovering older music I'd never bothered with before), and in terms of getting helpful info on different CD pressings that actually contain different masterings. I've lost count of the number of times folks have collectively contributed EAC peak levels for the particular pressings they own, which has enabled me and others to find the mastering we're seeking without having to pay through the nose for a particular pressing. These collective exercises also often end up piecing together interesting stories about the journeys certain digital masters must have taken around the world to end up as different pressings for different markets in different years.
So I take what's valuable from the Hoffman forums, generally ignore the BS, and occasionally speak up on behalf of the principles we believe in here. YMMV of course.
