Free Thinking, Free Learning
I've been a member of Khan Academy for about five months now. I occasionally log on and watch a few videos to see if I can further my awareness on subjects which I have never been exposed to; most of which seem to be things about finance.
If you have not yet been to Khan Academy then I suggest you visit it. It's free and you get to keep track of what you learn and test yourself with quizzes.
What is amazing about this project is how it got started. You can read a bit here.
But even more interesting is how much money we (as Americans) spend on education but are one of the worst countries in the world for learning.
