Since I'm not very experienced, I try to pay attention and at least make a sensible run that people can get around me on. A couple times I've ridden lifts with a skier that would tell me how to ride, the one I remember was a guy telling me how to ride moguls because snowboarders "don't know how to and scrape off the snow". I just listened to him and nodded. Meanwhile, a skier below us was scraping tons of snow off of Alberta Face right below the chair.
I just try to have a good time, and not get in the way of anyone else doing the same. And those condemning skiers would change their tune if they saw how often (especially for a new rider) I help out skiers by bringing their "yard sales" back to them.
