Not an ML expert, but is it feasible to train the weights using the actual Twitter feed as an oracle?

[minimaxir]

No, even if you somehow were able to download the corpus of all public X posts. There are many hidden signals that are feature engineered in good recsys, and the stripped-down algo won't be able to replicate them.

It would cost a fortune in API calls, so it's not practical for anyone except internally at corporate.

[bpavuk]

well, Bluesky and Mastodon posts would suffice, but it's still useless because of how redacted the release is

[VoidWhisperer]

I feel like bsky and mastadon only represent a subset of users, so I'm not sure how well you would be able to create a general rec system similar to twitter's from that that is useful outside of those places
