I agree, Kevin, it’s good to see Steem/it mentioned anywhere, especially, in serious literature.
My wife picked up a few books about blockchain & crypto currency to deepen her understanding. I remember how excited she & I were when they used Steemit as one of the examples, in her textbooks 🤓. May this go on to be a trend! 👐🏼
Yup DPoS is being used in some blockchain projects, like Steem :)
