Semi-weirded out...

I found out this morning that you can see where and how many people are looking at your blog. And I'm a little...what's a good word...concerned/interested? Like in the last week 3 people from Germany, 1 from Canada (which could be a friend), 1 in China, and 1 in India. I've been trying to create a more open blog while creating more privacy for our family (not listing last names, addresses, where we are) but our blog address is our last name. I can easily change our blog address, but it would make a little bit of work because I have to transfer everything over. Do-able but time consuming. I have a few blogs linked to mine that are other families, and I'm wondering if I need to take those off??? One of the "big time" blogs that I follow is a family blog who's address is the authors whole name. But she's careful to not list last names and doesn't have blogs linked to hers of other families. So..change name or take blogs off???
