Just to chime in here.. I _really_ like keeping notes on books now. I put them in my vimwiki, write it in (github flavour) markdown, and publish statically. Very handy.
Ah, vimwiki looks perfect. I've been swayed away from hosting my own wiki every time I considered it because editing is such a chore (opening new pages, delayed feedback, etc), but vim is the perfect environment for one.
