Here's an interesting article http://chronicle.com/blogs/wiredcampus/u-of-illinois-at-springfield-offers-new-massive-open-online-course/31853 in the Chronicle of Higher Education about free online courses that are open to the world.
I especially like the reference to how higher education could be changing so that universities become certification centers where students go to take a test to certify what they know instead of universities having the primary role of "delivering" knowledge. Students would independently choose what to study from a wide array of open content available from many different sources.
This kind of education and professional development makes eportfolios even more important to have and maintain. Keeping track of what you've studied and which certificates you hold could get to be quite a task over a lifetime. If you are interested in getting started with creating your own eportfolio, check out the instruction module I have posted at https://sites.google.com/site/eportfoliobasics/.
