X, formerly Twitter, is rolling out a new option to let users share their community posts with all followers. This is much like posting a message in a thread to the whole Slack channel.

An X engineer announced the feature through a post saying that it is available to users on iOS first and will be available on the web and Android soon. Users who want to broadcast a community post can check the “Also send to followers” option while posting in a community. The post will be visible to the poster’s profile as well.
