RE: When a vlog doesn't come out. All I tried was talk about Steem to none Steemians.

But... so would the internet and email in their early days! I started using the internet and email in the early 1990s. But I simply could not get my friends and family to understand what they were all about. I'm not a techy type, so I certainly wasn't blinding them with science or jargon. At my workplace there were four of us who were interested in it, and the others thought we were mad - their eyes would just glaze over.
It took a few years, but they got it in the end!I agree with @revisesociology that you probably know too much about the subject to explain it coherently. And it's not an easy sell. Steemit would fail the "elevator pitch" test.
