Threads, a social media platform under Meta, is launching a new initiative in the U.S. called "Gems," which will award a distinctive purple badge to public posts and replies that contribute to meaningful discussions. This feature aims to foster engaging discourse among users. Additionally, Threads has introduced "ghost posts," which disappear after 24 hours, allowing users to share temporary thoughts and receive replies in direct messages. Another feature, "Dear Algo," lets users customize their content feed for up to three days and share their preferences with others.
