Months ago, Twitter was testing an Instagram Story-like feature, called Fleets, but its release date was unknown. Fleets are basically Tweets that disappear after 24 hours, just like Instagram or Snapchat stories, and now, Mobile Syrup reports they are available globally.
The concept behind this feature is simply to make floating, momentary thoughts not permanent on the social media platform. Twitter hopes that this will make users more comfortable sharing their “casual thoughts, opinions and feelings”. Additionally, Fleets cannot receive Likes, Replies, or Retweets. That ensures they will not be circulating on Twitter. What’s more, they can’t be embedded on any external platform.
