Excellent post.
I would add Coursera.org and Alison.com
Both are for free online courses in multiple subjects.

I'll add quora.com.

It's basically Yahoo Answers but on roids. There's just so much knowledge and experiences you can read. I browse it daily and learn something new daily also.

I think you should add https://dash.generalassemb.ly/ it's basicly the same as codecademy

Dash is a project from educational institution General Assembly that focuses on building websites, specifically HTML, CSS and JavaScript. Like Codecademy, the courses are designed to be easy to get started with and very interactive right from the beginning—if you want to be able to jump straight in with as little preamble as possible then Dash could be for you. One of the spin-offs created by Dash lets you build your own custom Tumblr theme, which gives you some idea of where this resource is pitched.

You might not be able to launch a career as a freelance Web designer on the back of Dash alone, but it's free to use and friendly for beginners, and by the time you come out the other end you'll certainly have a solid foundation in browser coding skills. The step-by-step guidance and rigid structure of the course may feel a bit limiting at times, but if you want to be guided very carefully through the fundamentals of the Web then it's perfect.

#9: Insturctables - Learn to do just about anything!

You misspelled "Instructables," and it seems as if this thread was rushed.
