"/>Does anyone else keep their own knowledge wiki?
I've had a private installation of dokuwiki for years, but didn't use it for a large chunk of time. Within the last year, I've started using it again, and I really like it. This thread on lobste.rs has some great comments on the benefits of keeping one, and even more so, on making it public. Not sure I'm doing the public thing yet, but I'm definitely using it more and more.
The great thing about dokuwiki is, that it's just txt files underneath, so you can read and edit them with a text editor as well, if you prefer.
