Mondo, you bring up an excellent point. It is kind of funny (now that I look at it) that my first topic would happen to be on RSS and the significance of the disconnected paradigm and yet I present it in a format (video blog) that requires the viewer to be on-line.
There are ways around this. I wrote the only book on RSS, and am just working through the second edition: since I wrote the first one, there has been a lot of progress in ways to embed video and suchlike within an RSS feed. Drop me an email if you want some pointers.

RSS, though, is just the thing for a more productive way of life. Pretty much any repetitive information gathering exercise can be automated into an RSS feed. After reading GTD I started to go through everything I did during the day and coding up feeds for everything I could: I have private ones for my bank account and so on, and you can track FedEx packages in RSS or validate your site with tools I wrote and made public.

Actually, if anyone has any ideas for things that could be better done in RSS (which is basically a NextAction list with a fancy user interface) let me know. I'll code it up for you.
