November 18, 2020: Twitter on Tuesday said it was rolling out tweets which disappear after 24 hours, joining rival social platforms in offering ephemeral messages.

The new "fleets" which had been tested in several countries in recent months are "for sharing momentary thoughts" and aim to bring in users who want to avoid having their comments become permanent fixtures, according to a Twitter blog post.

"Those new to Twitter found fleets to be an easier way to share what's on their mind," said product manager Sam Haveson and design director Joshua Harris in the blog post.

"Because they disappear from view after a day, fleets helped people feel more comfortable sharing personal and casual thoughts, opinions, and feelings."

According to Mashable, the feature very much identical to Instagram Stories, which themselves are a rip-off of Snapchat Stories.

In March this year, Twitter started testing Fleets in several countries, including Brazil, Italy, India, and South Korea, and the feedback was probably good enough for the company to introduce them globally.
