I use X solely for the AI discussions and I actively curate who I follow, but where is there a better platform to join in conversations with the top 500 people

I use X solely for the AI discussions and I actively curate who I follow, but where is there a better platform to join in conversations with the top 500 people in a particular field? I always assumed that the reason legit answers often fall under "Show probable spam" is because of the inevitable reports coming in on controversial topics. It seems like the community notes feature works well most of the time.
