Why no threads on OTL amps?


I looked through the old thread list and didn't find anything on OTL amps. How come? Does nobody like them? Is there something wrong with them? Would you buy/notbuy one, and why? If you would buy one, which one do you like best? I always thought OTL was the best, but there doesn't seem to be much interest here on this forum for them.

I took my ZH270 to my local high end dealers' for him to listen to. It was sitting on a rack, and a customer came in and saw it and asked the dealer how he could cook anything in such a small microwave! Later, a little kid came in with his parents, saw the 270, and said "Wow! An EZ-bake oven!" True stories, but may also illustrate why the 270 sometimes doesn't seem to "get any respect"--it just doesn't look as impressive as some of the others, with rows and rows of output tubes in each mono-block.
I say to-MAY-to, you say to-MAH-to. Every time there's a discussion of OTL amps and the Berning comes up, the thread eventually evolves into a debate (to put it politely) over whether the Berning is 'really' an OTL. Who cares? Obviously, some people do, or the issue would never arise. But why SHOULD anybody care? Isn't the issue whether the amplifier, OTL or not, does its job well--namely, accurately amplifying an audio signal? What additional value--financial, 'bragging rights', whatever- would a Berning amp gain from being a 'true' OTL, or lose from NOT being a true 'OTL'? "A rose by any other name would still smell as sweet", said some famous poet.
By the way, I own a Berning 270, and love it with my Merlin Milleniums, whether it's an OTL or not.
Bill E., I made the same point in my post preceding yours, but since people obviously do care about whether an amp is an OTL or not, let me propose a theory (I should say that I'm an experimental psychologist by training, so explaining why people do things is what I'm supposed to be good at, although most days I wonder about that!:). High-end audio is a social group, a club if you will, and a fairly exclusive one. Within the club, there are 'levels of exclusiveness', kind of like becoming a 32nd degree Mason, or something like that. OTL amps have a certain 'mystique' about them, like they are the 'holy grail' of tube amplification. Being 'recognized' as an OTL confers this mystique upon the amp, and by extension those who own it. OTL owners are serious audiophiles in search of ultimate accuracy in amplifier sound reproduction; everybody else is just playing around.
Now, before anybody who might read this tells me I'm full of crap, I already know that--my wife and kids tell me that all the time.
I don't know whether I should post this or not, but here goes....

I read some comments by David Berning himself once about whether his amp is an OTL. I know, I should have the web address for this, but I can't find it right now. I will look for it. It was either on an old thread (2 years ago?) on Audio Asylum, or on a webpage by Gizmo Rosenberg (not sure of spelling). If I remember right, Berning preferred the term ZH (zero hysterisis) over OTL because of issues like those that have arisen here. I have seen Berning amps referred to as ZOTL's. Again, if I remember right, that phrase was coined by Rosenberg. Now, this was a while ago that I read this, so my memory may be faulty (gets worse every year, sometimes every day I think). When I find the address, I'll post it if anyone's interested. But really, like I said before, call it what you will--the issue is PERFORMANCE. When I get my tax refund, I'm planning on buying a used Joule Electra and having a shootout.
