>That could be the case, but I've seen too many instructors that know the intro stuff and teach full time, so they don't have the knowledge to past that. There are exceptions. I took an intro to C# class a few years ago and a fantastic instructor. We hung out alot in the evenings and are friends still today.

I would say, based on the course we had, that this guy was extremely knowledgable in many areas (and he teaches different courses). He is a developer himself, so he knows technology first hand. He has also a nice harisma and ability to keep the audience alert. Almost all our developers attended this course (all with different initial level) and everyone enjoyed it and learned a lot. Of course, once on your own, it's a different story.

>>This one was a really great guy and he knew the subject and everything else perfectly. I think I may have misunderstood something, besides, the course is just the 'Introduction', so I guess it was a bit simplified. But he emphasized the importance of separating the concerns, the ability to easily replace each layer, etc.
