ThinkerTools.com: "This site has two purposes: to promote our productivity tools, and share ideas about the creative process, programming, and other areas we enjoy. Our first product is Ovation Outliner. It is an basic tool that will help you organize your thoughts, and ideas." The site design kinda reminds of this one. I tried out the outliner. (It's for Windows, by the way, though that wasn't terribly obvious.) It's okay. Very simple. Obviously an early effort.
