Meta has introduced "ghost posts" to its Threads app, which disappear after 24 hours, available as of October 27. Users can create these posts using a toggle option that shows a countdown timer. Replies to ghost posts are directed to the creator's direct messages. Threads has also increased the text character limit to 10,000 characters per post and added group chat support for up to 50 participants, including customizable chat names and invite links. Multimedia support has been added for sharing photos, videos, GIFs, and stickers. Additionally, Threads is expanding its messaging features to users in the EU.
