Twitter is introducing "Birdwatch", a pilot program in the U.S. which is a community-based approach to help address the spread of misinformation.

Birdwatch will allow users to write notes in tweets to provide context to what they believe is misleading content.

At present, for this pilot program, it's only going to be visible on the Birdwatch site [birdwatch.twitter.com...]

We hope this will enable experts, researchers, and the public to analyze or audit Birdwatch, identifying opportunities or flaws that can help us more quickly build an effective community-driven solution.

We know there are a number of challenges toward building a community-driven system like this — from making it resistant to manipulation attempts to ensuring it isn’t dominated by a simple majority or biased based on its distribution of contributors. We’ll be focused on these things throughout the pilot.
