This is something I have been preaching for some time now and have found to be very true. We started using video as a micro learning when I was at T-Mobile about 6 years ago. It proved to be not only rapid and very cost effective but hugely effective. We need to reconsider much of what we make into elearning and use smaller bits of video or interactive content. And go mobile or social forget the LMS.
Here is the article that inspired this post.
