I think it is a benefit to have a public journal. You don't HAVE to give exact details...Just assure it is an
honest journal.
You can post a penny for your own thoughts on your own piece of paper, and ruminate upon it. Or, you can post a public journal and invite public comment, and may receive positive feedback. You may receive negative feedback as well.
I recall a time almost two years ago when I received advisories about what I should not do when I was having a bad time, through PMs. I had knowledge of what they were saying before they said it, but it was nice to see it reinforced. It may be why I am still around, much to the chagrin of some folks here. Just shrug them off and keep on truckin'.
Nothing ventured, nothing gained. Besides, trading can be lonely. Nothing wrong with having online friends around to liven up your thoughts.
