Amazing and free! This ought to make a lot of people happy and I like the social aspect of free hosting/sharing of screencast. The whole deal is a pretty neat trick using Java.
Screencast-O-Matic is the free and easy way to create a video recording of your screen (aka screencast) and upload it for free hosting all from your browser with no install!
The length is limited to 15 minutes but really that’s a good thing. I’d keep it way under 15 if at all possible.
