I'm not saying anything about shutting up... I'm just putting in my -0.02dBFS. I went through a "ITB" phase and other than the much more important "missing 'that' sound" I didn't like, nor do I currently like, digital limiting. And I'm a hybrid guy -- I don't diss the dig (pronounce "didge" like "ridge"). I sometimes do a fair amount of tweaking in digital before I go out into the analog chain. But those last few dB that everyone is clamoring for is almost exclusively (at least, here) added in the analog realm. If I could find a digital process that could mimic the volume portion, I'd do it in a heartbeat, as I could establish final levels before wandering into analog.
But I can't. So I don't. And it would open a whole other can of worms with the DA.
Add to that the simple fact that the vast majority of mixes just don't have the potential to be at "war volume" no matter who the mastering engineer is, no matter how experienced he might be and no matter what gear he uses. The best ME in the world is limited by the mixes he's sent. And most mixes don't have the juice. And I don't just mean "home brew" -- Most of the ones on the shelf in the store don't for that matter. It takes amazing core sounds, captured amazingly well, mixed amazingly well, etc., etc., etc. to be able to handle the 'abuse' of the 'loudness' portion of the mastering phase. Gobs of headroom at every conceivable step, the right instrumentation, the right arrangements -- It rarely just "happens."
