GTD TiddlyWiki is a small HTML personal productivity app. It’s based on the workflows and lists from the popular book Getting Things Done by Paul Allen, so you’ll find the usual GTD lists like Next Actions, Projects, Agenda, Waiting, etc.
I’ve always thought the idea of using a Wiki to keep your GTD lists seemed kind of dumb, but after trying out GTD Tiddlywiki I have to say I’ve reconsidered. GTD Tiddlywiki does a nice job of combining the speed and simplicity of a classic Wiki, with some nice user interface fluff like an attractive side bar menu (generated by the contents of a special Wiki page of course), window animation, disappearing/reappearing rollover menu bars, etc.
GTD TiddlyWiki is actually a slightly customized version of the original TiddlyWiki TiddlyWiki. The changes are mostly cosmetic, but I think they succeed in changing the *feel* of the application from an odd personal web page/notebook into something that feels like a real application.
I’ve been using GTD TiddlyWiki for a few days now, and I think it’s going to become my GTD/PIM application of choice. I like that it’s a lot more freeform than Entourage, I like that my data is stored in a nonproprietary format (HTML DIV tags), and I like that it’s cross-platform.
Almost everyone on the net has been blogging about how the future of web apps is DHTML and XMLHttpRequest, but I know I was still thinking in terms of feature enhanced web sites like Gmail.
What I’m now realizing is that the future of web apps may look a lot like the past of client server computing. The difference will be that rather than separate installs for each client application, the browser will be the “universal” virtual machine. Future web apps won’t be just feature enhanced web pages, but complete application that just happen to use HTML and CSS to draw their user interface and happen to use HTTP to communicate back to the server.
