Just as the title suggests, what wiki software (DokuWiki, MediaWiki, etc...) do you suggest to run? The purpose of this is nothing more than to make a remote note-taking sort of scenario, so it's not something for anyone but me to be used. I know I could do my own thing and stuff, but I'd rather get to know future software. Given how MySQL works, I don't really care if it's flatfile or not, but if it's DB it will make it harder to integrate when I switch to mongoDB later on.
Software/Hardware used: Linux, PHP 5.3, MySQL 5.3 (or 5.4), Lighttpd
