Not even a year since it launched Fleets, Twitter is shutting down the feature patterned after Snapchat and Instagram Stories. In a blog post, Ilya Brown, head of product, brand, and video ads admitted that they did not see “an increase in the number of new people joining the conversation with Fleets.”

Twitter said that it introduced Fleets as a lower-pressure, ephemeral way for people to share their fleeting thoughts. But it didn’t catch on.

However, Twitter is keeping Spaces, a live conversation feature that allows users to have a conversation.

“Using our learnings from Fleets, we’ll focus on creating other ways for people to join the conversation and talk about what’s happening in their world. Here’s some of what we learned and what’s next,” Brown said. “We’re evolving what Twitter is, and trying bigger, bolder things to serve the public conversation.”
