Working with some facilitators the other day and was asked where I source video clips I sometimes use for presentations and workshops. If I find them online I usually download and save the source in Delicious.
The wonderful Wes Fryer must have EBP (Extra Blog Perception) as he has generously posted and categorised a list of videos he uses on his wiki Moving at the Speed of Creativity...great stuff, I particularly liked "The Internet has Crashed"...thanks Wes.
Also my Delicious video links are online here. I have categorised these under themes eg: tutorials, comments, stories etc.
Another great place to start sourcing online video is from TED (Technology, Entertainment, Design) which brings together the world's most fascinating thinkers and doers, who are challenged to give the talk of their lives (in 18 minutes). These videos from TED are great discussion starters and have also been collated on YouTube as the TEDtalks Director's picks.
