To Facebook or Not to Facebook

I've had a facebook for a few years now and I thought of it intially as an innocuous tool to keep in contact with the people I love and to stay current with musical artists that I love. I've learned to be more cautious from these conversations and articles about anything that I post. The advantages of having one is I am able to easily to keep in touch with those that I love very easily and can keep up to date on music and lots of other things that I love but the disadvantges are that people out there probably now know more about me than they probably should.
