Thank you, kamikaze.  I think you've hit the issue on the head.  I would agree that it's very unlikely that all of a sudden skiers will change their lingo to use "fakie" and drop "switch".  I just wanted to put the straight facts out there for people to think about.  Only time will tell as to whether we should have rejected the term "switch" for backwards skiing.
I also agree that most of the posts on this thread are repetitive.  A couple of interesting ones though from HAGGA and Lanks.
With HAGGA's argument, I don't think it is sound, because when we ride forward we don't pop off our tips -- or at least we're no supposed to.  Same goes with fakie -- you're supposed to pop from the centre of you weight, which is no different than a riding forward pop.  I realize that many skiers, however, aren't very comfortable with skiing fakie into a jump, so they have a bad habit of leaning really far forward on their tips, almost to the point that their tails lift off the snow.  Maybe this is what is causing the confusion.
With Lanks' point, I will agree that many tricks will not translate directly from one sport to the other, such as with the mute.  But with the mute, the skateboarding version is the closest to the skiing version, hence the use of the common term "mute".  In the case of "switch", however, the skateboarding and skiing versions are actually contradictory.  I don't think that is a good precedent.  We should still attempt to keep lingo as reasonably consistent as possible.  To say it's open game to use any terms for any meaning crosses the line, and reverts back to the lazy rationale that "we've used switch all along, so lets keep using it."  Or worse, "switch sounds cooler, fakie sounds gay".
For most skiers out there, it's a no brainer: switch has always meant backwards skiing, because you only started skiing new school in the past 2-5 years.  But please understand that back in the mid to late 90s there were many of us who rejected the use of "switch" and preferred fakie because that was the proper term in other sports.  It was only because certain high profile skiers kept using "switch" that it stuck.  That's the history behind the word, and I think it's important for everyone to know it.  Had those high profile skiers also adopted fakie, then everyone would be using "fakie" and I don't think we'd be having this debate today because there would be no issue to debate.
Oh, and by the way, I am not the same guy as in SKEEZE; I actually haven't read the article yet, just this thread.
