I really don't care to do that, no. I'm not looking to convince anyone of anything, just stating facts. The level of access to decision makers in many industry-specific private FB groups is incredibly valuable. I closed several 6-digit multi year deals just because I was at the right private group at the right time. To dismiss FB as a useless tool and delete a profile is short sighted. As a business you owe it to your employees and customers to be where business is conducted. A big part of it is now transacted inside FB's walled garden. Deal with it.
