Each option has its pluses and minuses. My site will include everything I offer my regular class, including emails and announcements but it is an online site without any bells and whistles. The iTunes U site is the most polished in terms of offerings, but there is no forum for interaction and requires more work if you don’t have an Apple device. Yellowdig is a new add-on to my menu and it is a site where you will be able to access the classes and material and hopefully interact with others in the class. (You will have to register on Yellowdig and it is restrictive on what email addresses it will accept.) YouTube is the least broadband-intensive forum, since the file size adjusts to your device, but you will be able to get only the class videos (and not the material).
If you are wondering why I would disrupt businesses that I am part of, I have three responses. The first is that, with four children, I am a consumer of the products/services of these businesses and I am sick and tired of paying what I do for textbooks, college tuition and minor financial services. The second is that it is so much more fun being a disruptor than the disrupted and being in a defensive posture for the rest of my life does not appeal to me. The third is that with Asia’s awakening, we face a challenge of huge numbers and the systems (education, public and financial services) as we know them don’t measure up.
