I love your wiki! I do the same on https://wiki.thingsandstuff.org . Same reasons here, note taking and knowledge outlines. Mainly for Linux, making websites and other tech, but various misc. things I'm also interested in. Fairly organic and often incomplete, but hey, that's a wiki for you. It ties in with a bit of constructivist learning theory also, helping frame things, though I know I need to refactor more to smooth out how much each article covers.
