Here are some links to people talking about MOOCs and thinking about their use.
Class Central is a great MOOC aggregator and will give you lots of links and reviews of great courses.
My colleague Fiona Harvey wrote her dissertation about MOOCs, she's agnostic about them, which makes her an even more valuable source of information.
I'm on twitter @dotsandspaces if you'd like to stay in touch or ask questions.
If you would like to find out more, I've blogged about the talk in more detail - please visit:
