We're trying to create something like that for you. So far we have a few guesses.
People want to learn this stuff
The first assumption is that people actually want to learn this stuff. They may have different motivations ranging from job security to entrepreneurship but we are guessing that people want to learn web technologies.
People appreciate guidance
Most persons appreciate a roadmap and guided learning. To put it another way, the shortest path to working knowledge is best. Not that the shortest path is always to quickest way to learn, we don't believe that learning without understanding is that useful (is that even learning?)
