KhanAcademy.org is a YouTube based way to learn. It is a not-for-profit organization and the 1600+ video lessons are the work of one man! Great way to review something you have learned before but need to brush up on (say Calculus). Or you can learn more about something you think you know about but keep making mistakes doing (say investing). He also has dipped into explaining the credit/economic crisis and the United States attempts to overcome it.
It is unlikely that I will make this famous, it is already the most used learning resource on YouTube. It was also recommended very publicly by Bill Gates as a great way to learn. If you haven’t heard of it or used it before check it out. I’ll come back and post more information on this Learning Resource once I’ve used it a little more.
