document publishing (and an avr tutorial)

I have been looking for a decent web document publishing system for a while. I toyed with the idea of writing my own at some stage, but I have recently discovered instiki, a great rails sort-of-wiki. I have installed it (you can check it out at docs.jeremyherbert.net) on my server and begun to tackle my AVR Guide, something that I have wanted to do for quite some time. I mean, why should arduino users get all the fun ?
