There are three levels of visibility in livejoirnal: public, private, and friends-only. Many of my online journal entries are set to private, those are, as you said, for internal processing and private matters. I have the least interest to read those thoughts today. I’m more likely to reread friends-only posts which generated discussion with people who I’ve never met in real life, but who nevertheless became my good online friends. But in any case, if I were to open my journal today it would be to write new entries, not to read old ones.
