Video learning in so many modes:
I am struck by the wide variety of uses for video in learning that are on our menu as designers.  As I inventory how we are using video at The MASIE Center, the list is long and growing

– Video “YouTube” Story Segments.
– Video PodCasts.
– Video Reports – Webcam Captures.
– Produced Video for Learning Modules.
– Skype (on every one of our desks at work)
– Webinar Video Elements.
– High Definition Video Conferencing (up to 4 Megs)
– Telepresence Video (Beyond 6 Megs).
– Flipcam and iPhone Video Clips
– Webchat Video.
– Video Capture of Seminars and Classrooms.
– Video Keynotes Live and Asynchronously.
– Video Guests in Workshops and Conferences.
– Video Coaching.

The introduction of video into almost every aspect of our learning and work tasks is profound and “disrupting”.  As designers, we must experiment with these formats – looking for evidence and appropriate use cases and examples of when not to use video. Rising bandwidth, lowered equipment costs, ease of editing and growing expectations of learners will make video a profound component of our learning efforts going forward.

From DSC:
Wow. As you can see from the above listing (and this is a highly-targeted listing in terms of the scope it addresses, as it focuses just on video), there are so many ways to deliver content, to teach, to dialog, to share information, to learn…and these methods are constantly changing…thus the name of this blog, Learning Ecosystems.
