I learned from watching all of Snowwolf's beginner and intermediate lesson videos on youtube.
I've only been riding 5 times so to say I'm stil learning is an understatement. But, I was able to link my turns the first time out (after about 2 hours or so). I can ollie, albiet going slow and actually pulled off a 180 on an embankment this weekend. Rode up the embankment on the slope, ollied and pulled a 180 and rode back down the embankment. I was pretty stoked.
Oh and half the time I go out I go out alone. All of my friends ski and they don't want to go as often as I do. I enjoy riding alone though.
