Even worse than the flocks (gaggles?) of skiers who stop for a chat in the middle of a run are those who repeatedly stop wherever they feel like on the moguls, often after just a few turns. Put a few groups like that on a mogul run and it is ruined for pretty much anyone on a board (and good skiers too).

Boarding moguls requires keeping momentum - the time you are most likely to wipe is when going too slow or having to change lines abruptly because the person downhill decided to poop out four bumps ahead of you.

Falling down is one thing but intentionally stopping anywhere other than the sides or directly behind a slow ski net is a really bad thing to do, regardless of how many planks you use. Don't do it.

I'm also in favor of indicating by hand your intentions when there are multiple avenues available (such as turning into a mid-mountain lift instead of continuing downhill) to avoid potential collisions. Just because downhill has the right of way doesn't mean you will get it!

I'm a skier and it frequently annoys me that a lot of skiers don't check uphill before setting off from being stopped - skiers seem a lot worse for this than snowboarders.

Yeah, I saw a group of skiers stopped in the middle of a run last week and I thought that some had been hurt. They were confused as to why I thought something was wrong.
