Increased Privacy?

I just googled myself with Lily's name and my blog was the first option. I thought I was being so sneaky by not using my "real" name, but it's there. I changed the email address associated with the blog thinking that might help, but nope. Is there anything I can do to get more privacy other than going password protected? I really don't want to do that, but I don't like the idea of my dentist or someone I went to high school with or someone I go to church with stumbling upon this blog. I like to feel free to express how I feel without feeling like people in my "real" life are peeking in.
Do I have to just get over it or PW protect? Sometimes the Internet is icky. :)
