Blog Separation?

Since this blog gets higher page rank, lots of google/baidu searches will show results related to my previous blog posts. I don't say that's not good, actually it is a good thing. However, since my blog is exposed to more and more people, sometimes privacy is to be considered. I need some posts to be restricted only to close friends.

So, I am thinking about separate some private-issue posts from this public blog site to another place where viewer control can be imposed. Maybe Xanga.com is a good choice. Or I will install a Wordpress on my website. We will see.
