I don't post in this journal any original content that belong under friends-lock. But I changed the setting for my writing journal anvar to default friends-only. I suggest to everyone who has a similiar journal to do the same. (LJ FAQ: How do I make all my journal entries Friends-Only, Private, or Public?)
I may post the one or other public entry to give an indication what that journal is about but I don't want to use control of my content.
