Had more or less this exact idea for a website before, with the exception of using wiki for the main technology, and there being different paths to learning the material provided by curators. Essentially it'd say go to this tutorial, now this tutorial. Now watch this video. Now do this exercise. Very similar to online courses nowadays, except it all pointed to external links and volunteer contributions, and there'd be more than one path for learning the same material (probably with comments and ratings to help you pick which one to try). There's a billion tutorials online, but things get out of date, and you have to hunt them down, and some people might think one link is more important than another, hence the different paths. But I shelved the idea after seeing online courses getting better and incorporating a lot of my ideas.
