projects/home/recap/FEATURES.md has some interesting stuff:

In realgraph you can see some of the things they keep track of, which include what you have in your address book, total time spent "dwelling" and a few other interesting nuggets.

Wouldn't any such system depend on 10 other internal systems, 20 databases directly or indirectly, each affecting the behaviour of the recommendation engine. That makes me doubtful studying such a recommendation engine is any better than a purely academic exercise.

You gotta hand it to Elon - he actually did it.

If you look at the GitHub repo, most of it is READMEs describing systems, not the models or code subleties which actually give explanations into how certain weird behaviors on Twitter happen. (e.g. the preference of certain users in the For You tab. EDIT: bad example, since there appears to be a flag for that in the code, although it does not specify which users are on the list)
