Yeah they used to say digital photography was a joke too. All these "real photographers" who discredit new techniques (HDR is still very NEW to most phographers) are just too curmudgeon / jealous / intimidated that they've invested 20+ years into photography and can be trumped in some fields of photography by someone with a cracked piece of software and a dslr.
People can call it a cheap Photoshop technique all they want, but the real truth of it is, is that when any technique, even as "over used" on whatever forums people may frequent, hits the photography field, it's under deep scrutiny that it's not real photography, blah blah blah. The result of a picture isn't real in the sense of how photographs have been captured for the last 40 years, but neither has color correction, or faux vignetting, or desaturing/saturating images. Hell, let's discredit raws as well, I mean...if you didn't take the picture EXACTLY how it looked like through your lens at that very moment, then I'll be damned if you can change the temperature of it and call it real photography.
A lot of people need to give the whole professional photography stint a rest. For the majority no one cares how much money you've invested in lenses, or what kind of brand you stick to, or if you use a cheap Walmart tripod or a Manfrotto. I think people need to be careful shunning techniques so quick, they just sound like the old guy who couldn't keep up.
Oh and if you look back at when raw photography started to pick up, or photo editing in general, it was looked at under a microscope and hissed at. It doesn't matter. A lot of photographers I know getting paid to shoot use any technique they can to get the best available photograph possible. This isn't just car photography either, we have two BIG wedding photographers here in Las Vegas, and they both have an extension knowledge in post production. Guess what, they're getting paid $10,000 to shoot weddings. I guess they can't be all that bad...
Edit: with that being said, I personally don't care too much for overly cooked HDR's. But that's not to say all hdr's are good or bad, or only subtle hdr's are good. I think they all have their place. I think in any post technique moderation is key.
