I have been kind of unimpressed with vimwiki, so I used to just use my own folder structure for categories and create markdown/rst files for somewhat-formatted notes.<p>At the moment I'm using Zim wiki, which is a graphical program.
does "echo" count ? I do "echo mynote123 >> notes" occasionally when working with a codebase especially a novel one.<p>Then emacs org-mode for more structured notes.
