Yes, every one of these folks - mostly friends and family - has a Facebook account and are active users of Facebook. It is not the simplicity of having a textbox and a submit button that matters in this case - they all know how to post a tweet. It is that once they do that - nothing happens. In FB - a post often immediately gets a reaction - a like or a comment - even if they have only a few friends. The stuff you post on FB is not as transient - while your Tweet most likely disappeared in a few seconds from the timeline of your followers.
