Show HN: Community Detection on Bluesky

by thijser on 2/11/25, 8:39 PM with 5 comments

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.

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