Initial feedback based on a survey by stern agee shows the majority of users (83.6%) are unwilling to pay anything to make sure people see an important post. I wanted to see what you get if you do decide to pay; when I promoted a post; my promoted post gathered 2.9 times as many views but only about the same number of likes as my typical post of this nature."
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
