Yes, I love plain text. But for my personal diary I want to insert links to Internet sites and local files like pictures etc.
So I used HTML for a while. Now I thought about to use Org mode of GNU Emacs, and it's great. Really perfectly structured.
Well I wanted to switch to a new GNU+Linux distro today. But then I changed my mind and decided to stay with Linux Mint for the version 17. Will upgrade my Petra when the final release is available. So I had time to switch my diary.
Love it.
