I just read this in Wired Campus, and I had to immediately try it out - Sktechcast - a new blogging and teaching tool Just when you thought that online you could have an 'asynchronous' moment of white board plus audio', here you have it. No need to have everyone connected. This could add short audio with simple sketches that can be used over and over again. Great idea.
Very nice, indeed! It was a bit slow to load everything, but the easiness of drawing and recording was amazing.
To share, one can use a link, like with my own test here: test_sketch - Sketchcast.com But, one can also embed the sketch very easily:
