I discovered TiddlyWiki this week, and as the title says, WOW! If you haven't heard of it, essentially it is a serverless blog/wiki, implemented purely on the client-side (in Javascript). That's cool enough, but on top of that, it is head and shoulders above (in terms of user-interface) any other blog/wiki I've used. It is implemented as a single file (code+CSS+content), so it is trivially easy to carry around on a USB stick, etc.

Earlier this year I was playing around around a little bit with DHTML (trying to figure out what all this AJAX stuff was about). In doing so, I realized how much of what is called "AJAX" is really implemented in the browser. I had a vague idea that you might be able to write browser-only AJAX-ish apps, but had no idea they could be this cool. You can use TiddlyWiki as a blog, a wiki, a homepage, a bookmark collection, a todo-list, ... the possibilities seem endless. For all the times that I've opened up a text editor to scribble down some random fact (and then was never able to find it again), now I can use TiddlyWiki.

I'm currently playing around with learning how to write macros (Javascript + the TiddlyWiki framework). I haven't found any really good "HOWTO" sites about writing TiddlyWiki macros, so I may start one here over the next few weeks.
