Unfortunately the problem there with how you start. For example. My friends that I've managed to accumulate over time have FB or don't. A lot of my gaming friends, who would enjoy my content or any kind of YT content for that matter, don't participate in social media for many MANY reasons. I myself have despised FB for a lot over time. So the friends that I do have revolve around family, friends I've had when I was a child, co-worker's I get along with, and friends I've met on some MMO's. Most of these people don't straight out like the type of content I do, or frankly like YouTube at all which makes the whole, "Share with friends" thing moot. I think that this is a point that should be footnoted and not centralized. If you can share with friends, and they share your stuff, it's wonderful! If not I think most people, like myself, are looking for advice on how to move past this first stage of "Share with friends/family." and move on to what really matters beyond that for growth purposes.
