I've just realized that my article had already been published on TechTarget "SharePoint Training".
Let me make something clear, I am not a trainer, the reason I've chosen "training" topic is because in my experience the biggest obstacle in end-user adoption is lack of competence and general basic knowledge of the SharePoint environment and it's functionality. This can be addressed through delivering right training. Take a look at this article, hopefully it will help you to define and customize your training a well as explain different delivery methods.
