This is my first try at creating a map of lemmy. I based it on the overlap of commentors that visited certain communities.
I only used communities that were on the top 35 active instances for the past month and limited the comments to go back to a maximum of August 1 2024 (sometimes shorter if I got an invalid response.)
I scaled it so it was based on percentage of comments made by a commentor in that community.
Here is the code for the crawler and data that was used to make the map:
What is [email protected] doing over with the red dots 🤔
Either the people in [email protected] are pretty horny or its an artifact of the dimensionality reduction and means nothing.
Edit: Actually it could also be that it just didn’t collect enough data on that community and the most recent person was also active in nsfw communities. I was only able to get back 14ish days in the data for lemmy.world. They produce way to many comments and I got kicked out early.

Maybe it would be cool to have an interactive version where you could click on any two nodes and it would tell you the actual distance
Long distances actually don’t really mean much it can’t be guaranteed that they actually correlate to much. It is mostly the local groups that are conserved and a bit of the global structure.

This community has only two posts and a few comments. The algorithm has very few information on such tiny communities.
It would probably be useful to only include communities with a minimum amount of interaction to avoid such outliers.
