Twitter Fleets is designed to help users feel more comfortable participating on the platform in a "lower pressure way" Twitter said in its announcement.
Fleets is different from regular Twitter posts that remain on the users feed until they are deleted. The new feature is available globally now after Twitter first tested it in places such as Brazil and India.
