Oh man, I feel you. Over the summer, I went through ALL of my old journal entries and changed the authorization statuses (? how do you pluralize "status"...) to what I felt was appropriate for me now (some "public"s to "friends only" or "private" and some "friends/private" to public, etc...), sometimes adding tags, when I'd remember. I've had this mama-jamma since 2001, so that was quite a feat. (and one I'm SURE I'll do again).
