I consider his marketing tactics to be superb. He's got thousands of people right in his palm, he seems to know how to fit in with his right audience even though his products are something not even worth a tenth of what he sells them. Knowing what your market wants and being able to get to them faster than most will probably get you a level of success. E.g. Many business related books have exactly the same content he sells, but his approach to the right audience is what I would say "High quality".
