ZuluPad is a notepad on crack. It’s a place to jot down class notes, appointments, to-do lists, favorite websites, pretty much anything you can think of. The great thing about ZuluPad is that it combines the best parts of a notepad with the best parts of a wiki, a concept made popular by Wikipedia. The basic idea has been called a personal wiki or a desktop wiki.
Downloads are currently available for Windows and Mac OS X, and a Linux port is in the works.
