This will be the Nth attempted launch of instant outlining. This time I think we may have the critical mass we need to actually get it booted up. Also, instead of building on Friendfeed, I've written my own realtime engine based on long polling. It was fun to put together, and I think it will be quite reliable. Heh. We'll see.
Meanwhile Marc Barrot is making excellent progress at doing a browser-based outliner for updating Scripting2 sites. Marc is based in London (that's in England!).
