This is maybe a bit of a tangent - but you might like this project called "Azone Futures Market" - from a curation perspective they've done an interesting job in visualizing their daily influx in tags/topics... if the steemit tags evolve a bit maybe we could begin building some visualizations to get a curatorial eye on the scope of information that people are posting in a given day / week / month / year.... http://azone.guggenheim.org/
