Facebook has been emulating (read: copying) Snapchat for a while now, whether through Instagram or on its own. So, it shouldn't come as a surprise that it's at it again. This time the company is playing around with a feature for Messenger akin to Snapchat's streaks (direct snaps sent back and forth between friends, which come with emoji rewards). Twitter user @CaseSandberg spotted the experiment, with Facebook confirming to Mashable that it is in fact testing it, complete with emoji-like icons. The social network claims it's a way to glean fun facts about your pals, but it's clearly just a ripoff aimed at drumming up more engagement.
