I didn't read the user agreement (probably should have!) but I think if you don't leave your livejournal public then you don't really run the risk of anyone making a comment that could end up getting you sued. I have a hard time imagining a comment that would get any of us sued unless we had a really controversial blog say for political or celebrity gossip. On a different note, there are very few people I know anymore who use live journal and since part of my enjoyment over having an online blog is reading other I've thought about jumping ship too.
