I think using facebook to share those ideas is good enough because many people use facebook. Most of people, because they can access facebook even they don't have smartphones.
And I think OP's idea is to introduce to people who don't know the worth of bitcoin, right?
Few people know the real benefits of Bitcoin. If they don't have benefit, they will not use it.
I created this Facebook page to explain just that to the general public- the value Bitcoin will bring to them
Yes! The goal is to introduce Bitcoin's worth to people. This way when the content gets shared, more people will find value in it and when they find value, they will use it.
