I think it's funny to hear skiers give more props to skateboarders and snowboarders about how they influenced skiing. It's like so many are scared to admit in-line has a role to play in skiing.
First you don't need real style or need to do kick flips (or any tech tricks...) to 'look' cool on a skateboard, you just do. But they did create grabs and all other sports in that range followed. Skateboarding is the true originator of grabs.
Second, Surfing and snowboarding did bring what style was all about and all other sports in that range followed.
Third, in-line skating is NOT the sole influence for new school, but it is it's closest relative in terms of grind possibilities, stance and rotation axis.
So whatever you say, today's skiing has been influenced by surfing, skateboarding, snowboarding and in-line skating alltogheter. There's nothing wrong with that.
Most of you guys forget, that the sport is what it is today beause of skiers who where disatisfied with skiing and brought in outside elements, to shape it to their vision of what it should be. Wether it's skating, in-line or whatever, it doesn't matter, as long as the limits are being pushed...
After all this, if  you still think in-line shouldn't have a close relationship with skiing. Then you probably think the following skiers don't know what they're talking about;
Phil Belanger, Iannick B, JF Cusson, Phil Dion, Dave Crichton, Scott Hibert, Thomas Rinfret, Mike Nick, Nicky Adams, Chris Turpin and the list goes on... (there's a lot more)
These guys have either rollerbladed at one point or still do. Some have admited it in pubic and some only in private (some don't want to deal with the hater factor...). For some, skiing is like skating on snow, others it has influenced their tricks and style and a few have used in-line, strictly, to learn new tricks before applying them on skis.
I'm not trying to convert everybody to rollerblading. I'm just saying stop your paranoia and respect it for what it has contributed to skiing.
Lately, I've heard  more dissing coming from skiers than skateboarders (they're actualy giving bladers more props than ever) and it sounds ridiculous when it comes from a skier.
I'll stop now before I write a novel...
