If you’ve updated to the latest version of BBM, you’ll notice a new feature recently included which I think it awesome but depict Facebook.
This new features allows users to like display pictures (DP) and status update of their friends.
This change is recent and if you’ve not updated your BBM to the latest, you need to do that to enjoy this latest feature.
Atleast, it will make BBM now more interactive instead of just looking at the recently changed display picture, you can just hit the like button and move on. It works just like FB, you get to see the number of likes a particular DP has gathered and a notification will be sent to the DP owner to see his DP recent engagement.
I think this is a really nice update.
