You should check out vimwiki! I came from org-mode and have been using vimwiki the last three months now. It can do .md and export to html. I mainly use it for day to day notes and todo lists.
Thank you! Org mode has made me try to switch to Emacs for a while, but somehow have never been able to change my workflow, and Emacs is just to bloated to just start up for jotting a simple note... (I've found myself editing .org files in vim, which is just ridiculous!)
Maybe this will solve my conundrum!
