Slidecasting

Mike Arrington just blogged about tomorrow's launch of Slidecasting by SlideShare.  Slidecasting is a new media format, the combination of Powerpoint slides (everyone has the authoring tool) and audio (can be located anywhere), including podcasts (where it gets interesting).  While I'm a biased advisor to SlideShare, you will have to agree that multimedia on the web just got a whole lot easier and accessible.  And as objects you can socialize.

Here's an an example:

If I was an event organizer or podcaster, I'd be setting up a group on SlideShare now.

UPDATE: Launched, see the FAQ

UPDATE: Made my first Slidecast.  All it took was the time to listen to my 13 minute presentation while sliding some markers.  The editor UI is really easy.
