Yes, the web has really changed how education can be done. We have google, we have wikipedia... accessing knowledge has never been easier. I work since last year as a trainer, my passion is letting young college students be educated in a whole new way.(I am from China, I love my college time, but hate all the courses I was given) So I write blogs to let them understand the importance of freedom in their life and learning, I do screencasts to teach them some practical programming skills so that they won't go hungry fighting for their dreams.
I am very exiting doing all these. I do not need to repeat same thing again and agin. Teaching is now done cheaply and efficiently as never happened before.
