08/14/18 IMPORTANCE OF "SHARING" A POST
Sharing a post not only reaches your particular FB friends, it helps reach our FB mutual friends also, since FB limits the outreach of our TIMELINEs. In other words, most of my friends will never see any of my postings, even if they are important.
ALSO, someone we may not know personally could see a SHARED post. If it is an important, a really important idea, which probably won't be known by many people, it is a good idea to share it, to reach the unreached, while they are still reachable.
P.S. If I seem to be "reaching" with this post, it is because I AM.
