I’ve written here about a great personal wiki called ConnectedText. My review of a Mac personal wiki called VoodooPad is now posted at Mac Appstorm, which you will find here. I like VoodooPad a great deal. It is easier to use than ConnectedText, but is not as powerful. If you’re bi-OS and have always longed for the ability to do away with edit mode vs. the preview mode in ConnectedText, then you should give VoodooPad a try.
