Open Blogs

I have been a little leary by seeing all the people on the counter that look at my blog. I also had someone post to my first Naptime blog and leave her blog which was totally creepy. The quote on her blog was "evil is just live spelled backwards"??? I am contemplating making my blog private and just to friends I invite. I really enjoy sharing pics of the kids and would hate to water it down for fear of who is watching. I would love some input from you all. Thanks
