Some of us enjoy Facebook as entirely social. And if we are appropriately socialized we don't get into trouble amidst the relative lack of boundaries. Then there are those who leverage Facebook as a business networking tool. For them, the rules of connecting are more rigid - or should be.
Therefore, I am puzzled to find on such a Facebook site explicit religious messaging. That's a risk I wonder about. For example, this kind of outreach caused me to question that professional's business judgment. Remember, this is an era in which the late Christopher Hitchens was able to enhance his already iconic branding with his book "God Is Not Great." That meant there were enough agnostics and atheists out there to make the book not only a best-seller but a source of influence.
Those who turn to Facebook for marketing purposes have to figure out where the personal intersects with the professional.
