If you post stuff online, it's not safe and people looking for such information
will often make it known to others if they find it.
If you have a journal and put real personal stuff in it and leave it unguarded,
chances are someone going to find it and share your secrets.
Before you write out private things online or offline, give real serious thoughts
about what would happen if someone should find your journal... it probably best
to share your very private thoughts and stuff only with God, He won't betray you.
