Work in progress: how to think about the Farcaster channels opportunity

- <100 people groups and >1 million person audiences are well-served today by at-scale world-class mobile apps
- 100 to 1 million person groups are stuck with desktop-oriented apps like Discord and subreddits (cf. Apollo popularity)

Random reaction: would be cool if FC had low-level primitives for client devs to create something like "ephemeral channels".  Built on open-source SDK components that allow developers to experiement with algorithmically-generated, timebound channels. Channel metadata is stored onchain.
