Show HN: Community Detection on Bluesky (blue.facts.dev)

18 points by thijser ↗ HN
We ran the Leuven community detection algorithm on popular users on Bluesky (where the graph has edges determined by Jaccard similarity of a users' followers). We identified 118 communities and based on the names and descriptions of the top 10-20 users had LLMs generate title and descriptions for them. There are communities like "Feline enthusiasts", "Web Professionals", a bunch of NSFW ones and quite many communities are many different flavors of progressive/liberal activists.

I found all my friends under "Internet Weirdos" but I'm wondering why so few of us (myself included) are included.

At this point I only included accounts with >20,000 followers and the community page lists the 20 most 'central' users to each community even if there are more people included in the community.

"Internet Weirdos" sounds kind of negative, sorry about that, I'll see if the LLM can come up with something better. Or do you have a suggestion of what is a good name for your community?

"Extremist Voices" is worse! Looks like your your LLM meant "researchers studying extremism".

Surprised there's no Linux and open source communities. :(
