Apparently they came up with a name for what it is I've been doing with mikedaisey.com--apparently it's a tumblelog.
What's a tumblelog?
To make a simple analogy: If blogs are journals, tumblelogs are scrapbooks.
You can also look at tumblelogs as slightly more structured blogs that make it easier, faster, and more fun to post and share stuff you find or create.
You can find more information on Wikipedia.
I have to say, I'm not betting that this name takes off outside of rarified GTD-loving geek circles.
