title: Compare markdown or org mode
body: <p>I use Emacs for years, and nowadays, I write a lot of files in org mode, such as notes, plans/conclusions or something else. However but most website support markdown-style instead of org-style. StackOverflow is an example. :)</p>
  
  <p>Can someone tell me the exact difference between these two? Pros and cons?
  And which did you choose and why?</p>
