I've used several approaches to collecting and managing ideas over the years. There were URL browsing capture tools that put links into folders. There is of course each browsers ways of saving links. There is MindJet which can do this on your computer and then you can publish the Mind Map to the web. The are several mind mapping tools, The Brain is one that I tried for awhile.
But now I've found what I was looking for, with a few missing features. It's call PeralTree. Not that snappy a title. But it does what I need. Captures web content and arranges it into "trees" that can be navigated with a Flash PlugIn. You can share nodes in the tree with others.
It needs some more work.
- Interface with Outlook for emailing links to locations in the Tree
- A way to cross link, so navigation can move between nodes. That would make it a network navigator
But so far it fits the bill for the perfect idea organizer.
