Facebook Changing their policy re: private posts

Facebook is set to change their policy of all posts being private by default to making them public by default. As a marketing professional this is pretty heady stuff. The ability to target my advertising based on real-time information being posted by Facebookers is an amazing motherload. BUT..... and it's a big but... as a person using Facebook for personal and professional reasons, I'm pretty sure I don't want all my posts public by default.

Personally, I post... well, personal messages to my friends and family. Innocuous as they may be, they are not meant for public consumption. And professionally, on occasion I post my thoughts on topics for my clients to comment on. Again, these are not for public consumption but for a specific audience. If I want the comment to be public, then I make a blog post. My choice.... I chose to use Facebook this way because they had a system in place that allowed me to keep my comments separated and private. Now, I'll have to re-evaluate every time I want to post something.
