I don't think I quite understand you but apparently I'm the guy with the one of the worst ideas lol. On GoodnightJournal.com you can write private journals too! It's entirely up to you to make your journal available for others or yourself. Also I don't think sharing journals will ruin your life either. Check out couple public journals on the site with comments to see how people interact each other on public journals. You will see more positive aspect of it.
