There wasn't a box for 'confused mixture of friend and acquaintance' - some people on my friends list don't (as far as I know) read my journal, and I definitely consider them acquaintances rather than friends. On the other hand, the people who do comment in my journal (or who have conversations with me in their journal - some interaction, anyway) are more than acquaintances. I'm conscious that knowing someone through LJ isn't the same as knowing someone well in real life, though. So far I have met no LiveJournallers in real life, that I know of, anyway.
