I think if you keep the same structure (introduction, evidence, explanation, example), tighten it up and briefly summarise DI at the beginning it would be more effective. It looks like some people have interpreted your informality as a sales pitch so I'd tone it down a bit. Personally I found the post compelling and will look into DI more in the future. As far as I can tell, it ties with my own belief that knowledge is a set of skills and should be taught by breaking down those skills into components and training them (as you would any other skill).
