Handy as a pocket on a shirt. This collection of “lifehacks” (geekspeak for tips and advice) is worth a visit or two or ten—and because this is a wiki it is constantly being added to and updated by the readers. If you want to really explore the possibilities here, grab TiddlyWiki and put in on a flash drive along with Firefox. You have an instant journal. Or if you are into David Allen’s Getting Things Done, then you can download this thematic GTDTiddlyWiki .
TiddlyWiki is a classic collaborative tool. Start a dialog with a friend. Send them your TiddlyWiki (it is an html file). They comment and return. Each iteration is actually a webpage of growing complexity so that the knowledge is being managed as it is created. When the collaboration is done, the resulting page is posted. Does anyone appreciate the pedagogical resonance here? I think that one immediate application is in how it can work in tandem with email, leveraging it into an uncommonly handy collaborative tool. Include encryption and you have security as well.
