LocalLlama is the place. Really high quality people and discussion there and surprisingly collaborative. Very different than most subreddits.

How is /r/machinelearning

[ratedgene]

good but not as community-oriented I'd say as locallama

the machinelearning subreddit has a lot of great experts there.

/r/learnmachinelearning isn't moderated well enough
