Facebook might let you see when friends are writing comments in real-time

Facebook is experimenting with a way to show when someone is writing a comment on a post. 

The feature was spotted by Twitter user Amber Dickso on Friday. She shared a screenshot of the Facebook app on her phone. 

The bubbles appear to work similarly to Apple's iMessage, which shows you when someone is typing in a conversation thread. 

Facebook confirmed to Tech Insider that it's been testing chat bubbles for awhile. "We've heard from people that they want their experience on Facebook to reflect the real time conversations they have," a spokesperson said. "So we are testing adding a line above the comment box of a post that indicates when a friend is typing."

It's important to note that Facebook experiments all the time with tweaks like this on a small percentage of its users, so there's a chance these chat bubbles won't ever work for everyone.
