Radio Userland's Instant Outlining goes open-beta. In one window you can see all the outlines I've subscribed to. When one goes bold, that means it's been updated since the last time it was expanded. To see the changes, double-click on the bold line... It turns out to be a big deal if you're working with a group of people on a complex project... When you subscribe to someone's outline, expect to see time-based notes on what they're doing right now... The most successful I/Oers are ones who are constantly trying to improve communication, to guide the reader to what's important, but still provide enough context to be informative... Every ten seconds (configurable on the Prefs page) Radio checks all the outlines you've subscribed to by requesting the "headers" from the server that its stored on. The headers say how large the outline is. If the size changed, Radio marks the headline as bold, and pre-caches the OPML text of the full outline. See Instant Outlining for a more meaningful screenshot and my commentary.
