Would you like to do screencasts but don't have the software necessary, boatloads of time to edit or feel you don't have the technical knowhow? While attending EDUCAUSE last week, I learned about the Jing Project.
Jing is sort of Camtasia Light. It's actually made by the same people, TechSmith. You can do short screencasts with audio on the fly, easily, for free. You can then upload onto your server, the Screencast.com (Jing's) server (you distribute the URL to whom you wish), share in blogs, IM, etc. The screencast is immediately available. The only thing is that your screencast cannot be longer than 5 minutes. But you can do quite a bit in 5 minutes; not to mention that it's a good lenght for the average viewer' attention span.
