We’ve long been a strong support of wikis. (Especially DokuWiki — look for a future blog post on this great open source tool in the future.) Wikis are great tools for being able to quickly add test, a link hierarchy, images and links to documents by even non-technical people. Most also provide a version control system. Perhaps their biggest strength is in the ease of searching for terms and usage.
All of that being said, a hybrid of this great tool is TiddlyWiki. Described as a “wiki on a stick”, or a reusable, non-linear personal web notebook, these little single page wikis have a lot of potential as documentation tools and more. For several months after first discovering them, I used MonkeyGTD (MonkeyPirateTiddlyWiki+GTD) which has a “Getting Things Done” organization to it. Having just had training in the GTD method, it was my search for a tool to use with my new understanding of GTD that led to the discovery of TiddlyWikis. If you’d like to sample all kinds of different TiddlyWikis, go to TiddlySpot.com.
What I like most about this single page tool is the speed that it runs. No need for anything but a web browser and a place to store your file. Very slick.
