dochub: Where are the tutorials?
Sitepoint: The structure is messy. It looks like a blog, but a historical structure is awful for learning. I want topic categories. Also lots of things I don't care about - books, courses - I just want references and tutorials! MDN is better from this side.
I'm not convinced. You're not going to kill w3schools if you don't understand why so many folks go to that site.
Personally I didn't know dochub, and might probably get back soon on this site. It's clean, and the information is useful, but only when you already understand well what you're doing. It's not for learning the Web concepts. Also, it misses direct mention of browser support for every feature.
