Distributed Social Networks

Simple code and data to measure how distributed various social networks are in practice.

• hhi.py <file.csv>: Computes Herfindahl–Hirschman index - values closer to 0 indicate competitive ecosystems, closer to 1 indicate monopolies

• fetch-bsky.py: Scrapes PDS list and user counts from the main bluesky relay

• fetch-fedilist.py: Scrapes host data from the HTML version of fedlist

• fedilist.csv: Contains user data for the fediverse (ActivityPub), from https://fedilist.com/instance

• fedilist-fromhtml.csv: Same as above, but scraped from the HTML version

• atproto-bsky-relay.csv: Contains user data for the atmosphere (AT Protocol), scraped by fetch-bsky.py from the main bluesky relay

• mackuba.csv: Contains user data for the atmosphere (AT Protocol), from https://blue.mackuba.eu/directory/pdses and bsky number comes from https://bsky.jazco.dev/stats

• www/: Simple dashboard to display indices

• BIndex.md: A proposal for a way of measuring blockability on distributed social networks
