damn man, the idiocy and hypocrisy in your post has me perplexed. I guess I'll go about this sloppily, cause I dont really give a shit.
You must be pretty stupid to think skiing falls short while snowboarding, grandiose and supreme, is free of plagues of monotony, trends, conformity, blah, and blah blah blah. Perhaps your head is too thick to see just how skiing is, in fact, diversifying, year after year. You could look at the explosion of new companies catering to different realms of skiing as an example; not all are for the same preferences. Same with the media that is produced. Say, in 2002, a happy two plank person only had a few movie options to choose from, while now, a happy two plank person has a pissload more to choose from, ranging from all parts of the world, budgets, styles, riders, etc.
What bugs me the most is that you say that snowboarding is better because snowboarding is better at being trendy? Then what the fuck are you complaining about? Sorry, its pretty stupid to complain about trendy fucks in skiing when you say boarding has to openly borrow trends to make it so cool.
And when it comes to the myriad of styles within the sports, I'm sure I could take a general statement about many different styles within snowboarding, and easily to apply to skiing. Your problem seems to be multi-fold: you're looking from the outside in (to snowboarding), oblivious to all the trend whores, cock gagging of certain people/companies/styles; you seem to forget that skiing, or freeskiing as we really know it, has only really come to its own in the last few years, really breaking out only after the millennium, while boarding has nearly decades under its belt, so it is natural that styles/niches would be more diversified since it has had more time to mature and develop various bases; also, you seem to really base your rant on this site alone, neglecting that - while there are a bunch of wankers on here just oogling certain things - there is a significant variety of preferences, styles, groups, what have you. You get beyond this site, and you'll see that there is even more out there.
If you get onto the comp scene, locally to globally, in practically any sport, you will run into a bunch of shit where certain people of status get the edge because of... status, affiliation, whatever, while the underdog/unknown gets the shaft. It isn't exclusive to skiing. It is very prevalent in snowboarding, too.
Clothing... well, why the fuck should companies sponsor people if not to sell more shit? You think it's cool for companies to make money (unless I misread, which is possible), and this is one of the avenues. Personally, I find much of the athletic marketing in sports to be a bit disgusting, including in skiing, but hey, more power to them. If a bunch of cocksuckers want some inferior shit because their idol wore it, well, fine. It's stupid, but that's the name of the game. Let the sheep get their grass.
But I do have to agree with one little aspect: when some people start to kind of blow up on the scene, some do try to be so cool, and one of the coolest ways to show that you're cool is to have a strong mental deficiency; it's cool to be stupid as long as you're good. But... it exists in snowboarding. OMG.
Sorry, not the most eloquent and insightful response, but... get your head out of your ass :)
