+1 for vimwiki. I use it for everything, from taking notes and todo lists to writing blogposts. The wiki format just works so well with my brain.

My favourite features are nested syntax (highlighting for codeblocks in any language vim has highlighting for)

>since the whole thing is just markdown

I was going to write a complaint about how vimwiki uses its own markup language instead of Markdown, but I looked in the help file to be sure and now I you can set it to use Markdown or even Mediawiki instead (vimwiki-option-syntax). I like it even more now!
