Divya Manian gave a presentation yesterday at WordCamp Seattle about generating proper markup when creating output from plugins, and she mentioned a site called W3Fools.com, which is basically a protest against W3Schools.com. I didn’t realize until I saw W3Fools, but W3Schools isn’t actually ran by the W3C, and it contains a lot of inaccurate information. Further, it seems like they intentionally try to mislead people into thinking they’re an official source of documentation so they can sell their “certifications,” which have little to no actual weight in the real world.

They list several alternatives, but I like SitePoint’s the best, so I’m going to start using it in the future instead of W3Schools.
