It took me a while to get the gist of it but I think I finally understand it well enough. It is difficult explaining things like Steem Power to people but just tell them it's a website you can get paid for posting blogs and that should be enough to at least get them started.

The same thing happened with me regarding Bitcoin. When I first started, I didn't know much about it. The knowledge of how it works clicks over time as you keep asking yourself new questions. I don't think you can understand it all with one explanation.
