Hey.. For many-many years I always kept hand notes (notebooks or index cards) as GM to detail out my adventures and worlds. A couple of years ago I started looking at "mindmaps' and have been using them ever since. You can add images, notes and even weblinks if you need to. As you can see it's a nice way to visualize how everything is linked together and relates to everything else. The software I use is free for private use as well.. anyone else use this kind of thing?
