Meta Platforms Inc.'s Threads app is planning to introduce new features such as a desktop version and direct messages, as more than half of its users have left the app. The app, which is a clone of Twitter, reached 100 million users within five days of its launch but has since seen a significant drop in growth. Instagram head Adam Mosseri and Mark Zuckerberg have reassured staff that this drop is normal and are focusing on improving the app's features and algorithms.
