Save the Diary / Journal or Diary?

This is going to be a site about journals/ diaries. Paper and print, or digital and virtual, fiction, but mainly non-fiction. Creative and just plain handwritten text or journals with a more emotional purpose, like the journal I wrote while going through my divorce and later deleted (to my regret now).

Anyway (is a very good and well uses journalling word) this is coming soon. Mostly because I'm having some vision problems. I have written and collected content to post and post about.

If you write a personal narrative, do you think of it as a journal or a diary? Is there an official difference?
