RSS feeds as queriable neural networks

Jon Udell’s got another wonderful “screencast” up: The on-demand blogosphere.
I’ve been a fan of Jon’s since he was narrating his content-management system learnings for Byte Magazine. These days he’s pioneering a bleeding edge that the rest of us will get to only when it doesn’t require customizing one’s own interface to the degree he’s willing (and able) to do so.
So, his reports are like dispatches from the future and when he says we’re moving in a direction, I trust him.
Is anyone else using this screencasting medium the way Jon is?
