FB has been nothing but fun for me. I mainly started using it when my niece went to S. Korea for a year so I could follow her adventure. I mainly use it to keep up with family, which is fun right now because we have a lot of toddlers.
Since I keep it to family and a few friends I don't experience the drama. My family can hardly be described as drama ridden. We all keep good boundaries on FB as it's not the place to air our business.
