We decided to omit delegation talk because it was fairly advanced (you'll notice most of our Steem power is delegated), but I was completely wrong on the flag/down vote. I never saw the option to down vote so just assumed it was t there. That's why I say all the time we're idiots! Thanks so much for the massively informative post. Wish I'd seen it before we did the episode!
RE: We released our Steem podcast today - check it out and let us know what we missed.
