...and I'm confident they do in the world dominated by technology-oriented Radio bloggers, then I've got a whole set of terminology to nail down. It goes something like this:
-
Outliner or outline (an application/feature that exists within the Radio application and the outlines are the "data" created by using the outliner)
-
-
Google outline browser (don't yet have a clue about this one!)
2/15/98: Meet an Outliner. "I had to experience the usefulness of an outliner before I could envision using one, to advantage, myself." 
[Scripting News]
Then, there's the whole concept of K-LOGS. I believe John Robb coined this term. Today, there is more about the concept at his web site.
All of this, for me at least, has to do with learning enough about Radio and its advocates to be able to see which gadgets are merely gadgets, which tricks are for programmers and developers and which features are truly features with function and benefit for end users and groups of end users.
So far, I'm as impressed with the prospects of using Radio as a content management system for updating a set of Radio categories as I am with Radio's utility as a personal journalism/publishing platform. Outlines, Google Boxes and a whole lot of other stuff isn't likely to turn executives, professionals and other non-developers into consistent Radio users. This isn't bad - it just is!
Now, if you suggest that the objective at some level is to turn Userland into a household name, make Radio a "killer app" and provide everyman with a personal publishing system, then you might want to reconsider the time-sink associated with some of the gadgets. Otherwise, Radio will go right along impressing a certain subset of developers, a subset of technology professionals and selected (patient) individuals from many other walks of life.
