So, you ask yourself, what exactly is this "World Outline" capable of? A basic example should do:

As I mentioned before, this is very powerful stuff but desperately needs an improved UI.

Try this: Open your Radio Application (the app, not the web front-end) and click on File | New. You now have an OPML file open in Radio. Create a sample outline with whatever you line and then from the Outline menu select Add Link... Type the url to an ompl file, for example:

http://radio.weblogs.com/0001015/userland/scratchpad/states.opml

Keep adding stuff to your outline. Now, for the cool part, double click on the arrow icon that appears where you inserted the above-mentioned link: boom! the opml outline opens up inside your opml file.

Now imagine managing a project where each player keeps an opml diary... create your project outline, link to every player's opml diary and you instantly know where everyone's standing.

Enjoy!
