This is very difficult question to answer, and although I've been thinking about it myself for some time already, I' not sure I could provide an adequate answer, without upsetting someone. First thing I have to point out (and I'm not very happy about it!) is failure of educational system worldwide - science is something boring, impossible to understand and probably not true (conspiracy theories etc.). Mass media don't help us either. Solution? Proper marketing and advertising, unfortunately. We all know (although many won't admit) what are the things that attract people to some content - easy to do/grasp concept (eg. "Lose weight in these 3 simple steps!") and smiled, attractive people presenting the content. No, this is not the attempt of discrimination, just stating the obvious. If we are discussing proper promotion of science here on Steemit, I think that we need a very good science communicator - for example, man and woman presenters having a popular science vlog on Dtube. So my idea - making our own STEEMSTEM Channel on DTube.
