This is a different method, but for the last few years I've been using Personal Brain (http://thebrain.com http://thebrain.com) for note taking on pretty much everything I read. There's a free version available that is unrestricted enough for most uses. Think of it as a mind map where every node has the potential to be the central node and where connections can be made from any node to any other. Mine, for example, has several thousand nodes on topics from everything ranging from science to literature to my business ideas to pretty much anything else. Having everything in one place is great because I find that I'll often stumble on something I added months or years before and I can associate it with what I'm doing now. It often exposes patterns, reminds me of stuff I'd forgotten and it's fun to explore. I haven't found any other software like it. I'm not particularly anxious to replace it but I think some competition would be great. A web app or something non-Java would be interesting. I've written about it more here, and in several other blog articles: http://marcusvorwaller.com/blog/archives/2008/07/18/personalbrain-vs-mindmapping/ http://marcusvorwaller.com/blog/archives/2008/07/18/personal... . I also did a quick video of how I use it awhile back http://www.youtube.com/watch?v=eTNlRPAq3gE http://www.youtube.com/watch?v=eTNlRPAq3gE . Hopefully that doesn't sound too much like an infomercial, I'm not associated with PersonalBrain in any way, but I do really, really like using the software and I'm surprised it isn't used more widely.
