Disappearing tweets? Twitter now has a feature for that

First Snapchat did it. Then Instagram and Facebook jumped in. Now Twitter is joining in, too.

On Tuesday, Twitter said it would introduce a feature called Fleets, allowing users to post ephemeral photos or text that will automatically disappear after 24 hours. Fleets, a name that refers to the “fleeting” nature of a thought or expression, will roll out to all iPhone and Android users globally over the coming days, the company said.

Twitter said its main “global town square” service, which people such as President Donald Trump use to broadcast their thoughts to followers, remained its marquee product. But the company said it recognized that many users simply lurked on the platform and rarely posted.
