I've generally really loved w3schools for their tutorials -- I've been using them to teach my kids web programming and whatnot recently and generally been happy with them. Is there something I'm missing about it? Maybe it's because we have really good ad-blockers running, but their content seems fine and (generally?) not terribly "lifted" from other sites (I.E., just SEO spam).

Is there a replacement for them that fills the same gap for web reference / tutorials?
