Zim - A Desktop Wiki http://www.zim-wiki.org/ http://www.zim-wiki.org/ Mostly because it just creates a bunch of .txt files, which are easy to handle (sync, backup, read via ssh, ...), and by placing them in subdirs you get a hierarchy. It is mostly for text, but it supports links, links between notes, links to files, pictures, code, lists, checkboxes, latex, gnuplot, ... and if you really need something you can create your own tool.
