There's topanswers.xyz/ as alternative, but I don't know of any #federated alternative yet.

Maybe @samcarter knows if that's something that have been discussed?

Actually since yesterday I'm pondering about the idea to build a #federated version of stackoverflow, nothing written yet, I'm reading, researching.

Also, right now I was checking this stack exchange sqlite db under CC BY-SA 4.0 to check how useful and doable would be import this data and using as a base for the federated version.

Also wondering if we could use this data somehow to train our own opensource AI to help the community, but I'm do not have knowledge on LLM/AI things. Please if there is any expert I would appreciate the opinion on that.

EDIT:

A better place to download the dump content, with more interesting tables, like the one with the Votes; the other link the dumped data only contains two tables Users and Posts. Right now downloading the whole data related with stack overflow, and will take some time due my humble home internet connection, so I didn't have the chance to take a look at the data, but I guess that's the interesting thing.
