According to Facebook's own advertising department, on the average, about 15% of the folks you imagine are getting your stuff are getting it. The other 80 or 85%..... not. That's one in five if you're lucky, one in seven if you're not. Ever wondered what that “promote” button at the bottom of your posts is? That's the doorway to talking to ALL your followers or friends or fans. It's the ONLY doorway, and it's a toll booth. This is not a bug, it's a feature.
