Community note: Community notes started as Birdwatch in 2020 and got released to wider community in March 2022. Elon Musk initiated the take over in April 2023, with any effects taking much longer. While Community notes got much more popular under Elon Musk, they're not "Elon Musk's feature". Aside from that, it's one of the social media features I really love and they seem to work surprisingly well. They have some issues and sometimes are slow to appear while people keep retweeting lies, but... it's better than anything else I've seen so far. The self-balancing (less impact from votes from people in a given segment who may be too biased on it) is probably what keeps it in check.
