Birdwatch, whichhas over 10,000 contributors, has been in a more limited pilot for months.
Twitter users not contributing to Birdwatch will also be able to rate notes as helpful or not.
Birdwatch’s effectiveness seemed to cut across the country’s political divide, according to Twitter’s data.
Twitter is looking toexpand its pool of contributorsas well.
Some third-party analyses showed that most Birdwatch notesdidn’t cite sourcesand raised concerns about Birdwatch contributors' anonymity.
At the time, Twitter said that most notes cited sources and that anonymity protects contributors from harassment.
Twitter hasplaced the algorithm that powers Birdwatch on Github, where it is publicly accessible.
