Reputation is a broad term, but context-specific reputation is often most helpful in discerning relevant information. Farcaster channels opens the door for developing contextual reputation

While "Top Casters" Is one example of badging, I expect more complex reputation systems to emerge on top of open Farcaster data

Context-specific reputation e.g. domain expertise

Who do you trust in the Dev channels may differ from those trusted in Music or DeFi and even within Subtopics in channels. 

What systems or metrics would be most helpful within Farcaster?
