I'm a big fan of Insta Stories, it's addictive and these results show Facebook continues to be the dominant platform. 

These results might be surprising to some, given the mixed feedback Facebook has faced in recent months. WhatsApp's Stories feature is catching up with 500 million dailies - I've personally not tried WhatsApp's Stories - Insta Stories is enough for me at the moment and I like to keep the platforms separate. No doubt it will catch up though based on the success of Insta & Facebook.
