You are judged by who your friends are.
In the case of Following
You are judged by what blogs you follow.
If bloggers can see you, they can see what blogs you Follow. And, they can see who Follows those blogs. Did I hear someone mention "Nineteen Eighty-Four"?
So, it bears thinking that you might want to resist the temptation to Follow the kinky lifestyle or blatant abuse blogs, if you hope for a lot of friends at your church to Follow your blog. Similarly, folks who Follow kinky lifestyle or blatant abuse blogs might present a problem, if a lot of that type choose to Follow your blog. Remember, Following provides 2 way links, between the Followed and the Followers. Does anyone remember "Six Degrees Of Separation", a few years ago?
This blog should probably be hidden, using the Edit User Profile wizard "Select blogs to display" link. It's private, so the public has no need to know about it.
My Humble Opinion, anyway.
(Update 2010/05): In a little over 18 months, a number of selections have been added, to let you control your security and visibility as you Follow each individual blog.
