Small, decentralized flows of information are most relevant for small, local communities.
Large, bulk information flow (like the stuff shared on nostr:npub10uthwp4ddc9w5adfuv69m8la4enkwma07fymuetmt93htcww6wgs55xdlq for example) can be done efficiently through large, central channels.
Good to have the flexibility for both … network effects are critical for smaller information flows.
