Elon Musk announced that Twitter's blue checkmark will be available for $8/month as part of Twitter Blue, which also includes priority in replies, mentions, and search, as well as the ability to post long videos and audio. This move aims to democratize the verification system, which was previously based on notability. The price point was chosen after considering feedback from users, including author Stephen King. Musk believes this change will help Twitter generate revenue and reduce its reliance on advertisers.
