There’s this thing called TiddlyWiki, and despite the ridiculous name, it is – as the kids say these days – the best thing ever. Basically it’s Wikipedia, except it’s just on your own computer, so only you can edit it, and you start with a blank slate and make the articles about whatever you want.
It’s a great way to organize free-form knowledge and ideas. I’m using it for Crane Girl now – characters, settings, plot, etc.
It’s possible I might be a little obsessed. But then, that’s nothing new.
