To make a point about hoppy beers, go try Three Floyds "Pride and Joy." It's a claimed 35 IBU, and has a teriffic hop flavor and aroma.
Sure, anyone can toss a ****load of hops into a beer, but the same can be done with malt. I think it comes down to recipe formulation. It's all about making things blend. Some beers exist just to showcase the hops, some exist to showcase the malt. Some exist to showcase the yeast. They're all good, and it's just a matter of taste.
I also fail to see how you can chalk hoppy beers up to marketing. First of all, how can homebrew be marketed? And if we're talking about micros or brewpub beer, I'm willing to bet that 90% of their sales are of their mildest, lowest IBU beers regardless of what kind of big hoppy stuff they're advertising.
In the micro/craft/botique beer market right now, the biggest hype revolves around Belgian styles, IMO.
I think this thread has ventured far from the original poster's intent. Yes, there are some rediculous IIIIPA recipes out there. But hoppy beers have their place, as do super malty ones, Belgians, etc. And if you haven't done so, you all should try a Pliny or brew the recipe Dude has done. It's friggin' incredible.
