I'm excited to see a competitor to W3Schools if only to have a more useful, up-to-date index.
That said, a large part of the problem newcomers have learning to program is not the available materials, but rather the reason. I've seen many people start these tutorials but fail to complete them. They wanted to learn to code because it's something they want to know how to do, not because they had something to build. Programming is a means to an ends, a solution to a problem.
I'm not sure what the solution is, but a product that started with the reason why someone is learning to code or, even better, could give them a reason, would be very successful.
