This business of "learning" piano technique by use of web resources smacks of artificiality to me, on the level of the "Learn to Play the Piano" Book/DVD/Computer SW that one can buy in famous chain bookstores.

Can you imagine someone wanting to learn Ballet by the same method? Or firefighting, or heart surgery? If one wants to devlop mastery over the piano (this is the purpose of "technique" and I mean "over") one should become a pupil of a good pedagogue. It is absolutlely necessary to have the eyes and ears of an expert doing real-time evaluation and feedback/instruction when one is in the early and intermediate stages of trying to climb
Mt. Piano Technique. As J. Lhevinne said, "there is no going under it, around it, or through it." [paraphrased]
