As I see on the forums (not just bitcointalk but others), most activity is around mining and following that is talk about buying/selling bitcoins.
between the lines you can sense the "get rich quick" idea
With the exception of certain big bitcoin voices like andreas antonopoulos (and some others) there is little to see in the long term humanitarian activity. Yeah there are people speaking out, but they do not attract the masses (and I mean the masses already using bitcoin, not regular "consumers" that never heard about it).
I think more time has to pass so people start seeing this bitcoin phenomenon as something more than bringing them $$$.
