Great work. I think more forays into search engine research and development should help a lot in connecting content consumers with content creators. And the way you are referencing PageRank is a promising start.

Hopefully more developers look into solving the current problems of content discovery as I feel that a good solution to the problem would be more valuable to the ecosystem than another generic application. Steem is like the internet prior to its indexing. There's so much potential in finding ways to map and span the network in new and innovative ways.
