My prediction is that Steemit will have a remarkable effect on all other social media, users will no longer be happy with getting nothing in return and eventually they will get accustomed to earning money doing the simplest activities (like, share, post).

I think you may be right. Once a large portion of society is earning supplemental income (or primary income) from sites like steemit, it will be very easily taken for granted. It actually takes effort to not take things for granted. @ironshield
