Hey, hey, we are joking here - the post was not meant to be extremely serious

- so no problem.
But I disagree to your last sentence. One can IMHO indeed become a better snowboarder by reading, talking, thinking etc., even without (!) practising (for some time). Sounds silly? I would even dare say that a large part of advances can be done by "pre-thinking" a certain technique, visualizing it correctly and building "images for the mind".
When done properly this is very helpful: It has to be trained, but once properly applied one can think about a certain change one wants to get in his technique, and next time one gets on the snowboard the technique *has* changed. Not a miracle, just applied psychology.
And from a certain level on it is (at least in professional sports) even the only way to further improve, I think. Many professional athletes spent hours per day just visualizing the movements, feeling of the muscles etc. before going out and practising.
Of course, at some point one has to practise these mental images, and the ultimate goal is to do all this out in the snow

and not only sitting in front of the computer, thinking of EC

One can discuss whether we have arrived at this level already. We are not professional athletes, yes, but just thinking a lot is not lost time or somewhat esoteric, I would argue (based on my own experiences in my earlier "high level" sports career).
What is mostly done - "ad hoc" thinking, if at all, on the slope during the ride, will take much longer to improve style and probably not lead to similar good results.
