While I was trying to explain Busy.org to my mother, I was struggling to find a simple way to explain it. Then the idea of a train emerged to my mind in a flash. Everyone understands how trains work, and a fast-moving locomotive seemed like a decent analogy. Busy is one train, Steemit is another, and they both use the same track (blockchain) and they are also fueled by the same energy source: Steem.
