I hope that they decide to keep adding to the tutorials here (not much so far)... but if you'd like to see what LEGO is currently offering in terms of Technic training, check out the links below:
Intro to Technic - some simple discussions.
Technic Tutorials - 3 so far. They indicate more will be created.
Technic Glossary - again, not much... very simplified definitions.
Combining Elements - discusses mixing Standard Lego Brick with Technic
