On: Ask HN: How do you manage your knowledge base?

I use a text based wiki synced via git. The advantage for me to use a text based system is that I can access it from different text editors, without the pain of custom vendors formats. For example I'm currently using textmate with this plugin: http://interconnected.org/home/more/2007/05/textmate-wiki/ but you can find macros for all the major text editors.
