FreeMind is a simple, elegant productivity tool - it basically allows you to quickly generate a "mind map" document. This is essentially a pleasantly laid out tree structure that packs a lot of information into a little bit of space. You can decorate the nodes with icons that have meaning for you, and also add a hyperlink to the node. Keyboard shortcuts are excellent, and clearly these folks went to a lot of trouble to keep the tool simple and easy to use. Really pleasant to work with. I'm starting to organize my task lists and so on with it, and that's going well.

I just wrote a little blurb about the Performancing add-on for Firefox. It's a little add-on that allows you to post to your blog using a rich text editor, spell checker, etc. Seemed kind of handy. Unfortunately, it chose to add a little "powered by performancing" line to the end of my post. Not appreciated, so I've uninstalled that one. What posting tools do you use?
