You said many things, but one of those, I consider it is important education in principle when you get to hive, if possible before. For many retire without even knowing what commitment means, even more critical is the one who stays for years and still has not noticed that there is something beyond posting a post.
On the other hand, it is important to bring people to Hive, I do not know if those who are on Facebook. What I do agree is to make it easier in some way. Oh and one last thought, advertising can help a little to have visibility although many do not like it, we should try not to make it so invasive.
