I'd say that my LJ is quite private. I'm not keen on everyone reading what I'm saying or thinking at that moment, which is why it's f'locked, but I'll share absolutely everything with my friends. I love and trust basically everyone on my f'list, so I don't mind sharing things with them. If I want something to be public, then I'll post it like that, but otherwise, I prefer to keep everything between my little network of friends.
