I was recently reminded of something I knew as early as 2001. It was the fact you can learn from MIT for free: online. If you check out http://ocw.mit.edu, there are at least 1,550 courses available online from MIT (as of November 2006) from subjects ranging from Business to Science. I was reminded of it again because I was teaching my Master’s class & explaining to them they can learn for free any day from even the best Institutions in the world.
Open Courseware (OCW) from MIT was started in late 2003, but they made announcements as early as 2001.
Don’t forget, the #9 site in the world (according to Alexa.com) is also Wikipedia.org which can teach you similar “free things”. They also launched a site: http://www.wikiversity.org/ to do something similar for free.
