A while back, I started using docuwiki as a personal knowledge base. Started adding things such as memorable quotes, ideas, understanding about concepts etc. Its easy to structure information using hyperlinks and each page contains bulleted information about one topic.

I am not too concerned with internet availability/mobile accessibility. The idea is just to document stuff that I can access later.

I don't think so. My experiences with Dokuwiki is not great. Its WYSIWYG editor isn't integrated properly, switching back to Markup doesn't work without a page save, so a lot of useless clicks. Furthermore I wasn't convinced about Dokuwikis mobile interface, not even speaking of the inability to use the editor then.

I use doku for my world building and other related notes for my fiction writing. Works great.

thanks for spreading the love :)
