We kept up to 400 of each channel’s most active casters from the past year.\n\n- Added the accounts that group follows most, one hop out.\n\n- Pulled 90 days of casts, reactions and app keys for everyone, straight from a Snapchain node.\n\n- Compared the days since Oct 15 with the same number of days just before. “Normal” is the same test run on an earlier window, so we know what a regular week looks like.\n\n- A random sample of 10k FIDs is the check against the whole network.","farcaster":"https://farcaster.xyz/ramitphi/0x79d8a22f94f58ead2d171e46ac4d7ca09ab56de5","firefly":"https://firefly.social/post/farcaster/0x79d8a22f94f58ead2d171e46ac4d7ca09ab56de5"}
