That of course turned out to be a bad decision as when Google bought YouTube they canned Google Video and all the uploaded videos along with it.
Well, I have at last tidied everything up and seem to have only lost one or two of the videos. You can find them here on YouTube as playlist.
Or you can view them on the embedded media player on my website.
If the mood takes me when I next get the opportunity, inspired by this blog post Cracking the KM code: start by asking why not what by David Griffiths, I will shoot a few more videos and ask the more interesting question "Why do we need Knowledge Management?".
