After thinking it through a bit, I agree that discussion should be open. If everyone posted with the 'it's the skiing, just the skiing' tone and intent of Liquid Feet, there would be no problem. Her posts are inquisitive, non-judgmental, and as such, an excellent catalyst for thoughtful discussion. All in all, I can say that there are plenty of diamonds found in the rough here to make it worthwhile, but I do think the general tone can use some self-reflective attention.
First off, we need to work on objectivity. 'What is the skier's intent?' vs, 'well, I just don't like their skiing because they're not focused on what personally interests me'. The former is how we start MA discussions on the hill, particularly with people who are very proficient skiers. The latter IMHO, is the problem. Some basic guidelines for MA might be in order. I agree, for full time ski professionals promoting product, services, organizations, or themselves, I don't think we need their permission, and I'd guess much of what is written about their skiing might be viewed with humor by those skiers if they were to read along with us. Where MA is completely inappropriate in a public forum is using clips of recreational skiers in fun, stoke, or travel posts for fodder and all too often thoughts that devolve into ego driven ridicule.
Now why the reaction on the moderation front? We're living in an incredibly stressful moment in history. For most, including myself, skiing is about simple joy and re-creation... connecting with the hill, our friends, and continuing to pen our personal histories and journeys. I started teaching alpine 10 seasons ago as a way to pay forward after surviving a close call with cancer. I've had that 'this may be my last run' moment, and as such, take NO time on the hill for granted. When reading instruction threads that go off the rails or smack of ego driven 'analysis', I tune out and walk away. Through the lense of truly life changing challenges, I have a pretty short fuse for things that really don't matter. On occasion, I voice frustration. We're all in a similar spot in that we don't know what this season will bring, whether or not we'll see distant loved ones any time soon, have a job or not, and for some less fortunate on the health front, whether they'll see a full, beautiful, winter.
Guideline?
Sure.
What are the skis doing on the snow?
What does the skier do effectively? What would we like to see change, then 'why', and finally 'how'.
Trouble seems to come in the 'what' and the 'why' as skiing is often viewed within the confines of narrow personal interests and immediate goals, a la if they don't ski like X, or release like Y, then they aren't any good, which quickly gets voiced (intentionally or not) as 'I can't believe anyone thinks this is good skiing and I'm going to tell everyone why I'm right'. Anyhow, I do hope the powers that be allow the instruction forum to continue and that we all work to address and improve the tone and tenor of the discussions here.
