I have personally found that Tizag[1] provides a much better HTML, CSS, PHP, and MySQL tutorial than W3Schools while still having a really easy to navigate website. Instead of reinventing the wheel all the time, maybe we should all focus our efforts into making the Web Platform[2] better or encourage people to use higher quality websites like Tizag.
