After my own heart right here. I followed some version of Luca Hammer's guide to categorise everyone I followed on Twitter into communities, then created rss feeds of them using nitter. It was fascinating seeing how they clustered together. I think I still have an old gephi file with that output. I did this before Musk bought Twitter, since I knew he was going to wreck it.

Basically, I would have killed for this tool.

(I'm now wondering if anyone's published a guide on this for bluesky.)
