@hope815,
What I've done is gone through all my account and privacy settings and locked everything down so it is only visible to me.
I also made lists in which to categorize my FB friends into common interest categories for things such as family, special people, politics, media, games, gardening, cooking, music, etc.
When I post something on my wall, I select which lists I want my post to be visible. If I post something about the games I play, only those that play that game see the post. If I post something for only family or special people to see, I select only those lists for viewing my post.
