I think you're missing one important point, and that is that in the STEM field, some people write primarily because the writer has gained new knowledge in which case, writing it down is both an excellent way of sharing and committing it further to memory.
Within the context of Hive, it would be the more selfish latter reason as no one reads anything of substance anyway. Spectrumeconomics is one of the best serious topic writers on Hive and the engagement on his incredible posts is appalling.
More proof if any were needed that 'rewarding' social media, or blogging is an epic fail. It breeds shallow posts purely designed to reap maximium benefit to the 'creator' . A shame as Hive ought to be a breeding ground for open debate and multi-opinioned writers on any number of topics but is generally just a place to post your holiday snaps.
I read you, because whatever you write, you make it personal and you are very readable. Long may you continue.
