Twitter testing new disappearing stories feature with Brazilian users

Twitter is taking on Snapchat and Instagram on their own turf.

The social network on Wednesday announced that it will soon be testing its own version of “stories,” or posts that disappear after a set amount of time. Dubbed “fleets” in Twitter lingo, the new, disappearing posts will be the first other than tweets to appear on its platform.

Stories, which can range from videos to text to polls, have proven wildly popular since Snapchat created them in 2015, and were quickly copied by rival Instagram.

Fleets will be shown above the regular Twitter feed, and share a similar design with Instagram and Snapchat stories. Users will be able to post disappearing text, as well as photos, GIFs and videos on their fleets.

The setting is being tested first in Brazil, according to a Twitter blog post.

“People have told us in early research that because Fleets disappear, they feel more willing to share casual, everyday thoughts,” the company said. “We hope that people who don’t usually feel comfortable Tweeting use Fleets to share musings about what’s on their mind.”

The announcement comes just days after reports emerged that activist investor Paul Singer is looking to oust Twitter CEO Jack Dorsey.

Among Singer’s main concerns, according to reports, are Dorsey’s divided attention due to his role as CEO of both Twitter and payments company Square, as well as Twitter’s modest stock growth over the past few years compared to its rivals.

Twitter is currently worth close to $28 billion, while Facebook has a market cap of nearly $550 billion.

Shares of Twitter gained 3.1 percent on Wednesday, to $36.
