Hello @matthew,
great to meet you!
Citizen.Fact sound very interesting would love to hear more about it. In connection to that maybe this project by another community member could be interesting for you: Introducing Oliver, WorldBrain.io, Memex and Storex, Democratising Knowledge
Great that you have such a clear goal for the Overweb Challenge with the website and desktop client.
How are you approaching this algorithm you are referring to?
@JollyOrc has been looking into how to break such bubbles but looked more at methods utilising human community management teams. (Social Media is broken, let's do better!).
What do you see as the key to your algorithm? What as the biggest challenge?
