Instagram becomes the fastest growing social network and the robots set to give you fines

Instagram is now officially the world's fastest growing social network - boasting 700 million monthly active users worldwide. 

Just in December last year it had 600 million, gaining 100 million in four months. 

At this rate by October the photo-sharing platform will hit over a billion. 

Meanwhile, security firm Knightscope has just launched K5  the robot set to patrol parking lots, offices, and malls. 

Like something out of Star Wars or Doctor Who, K5 units have already been deployed around the US and are set for worldwide release.
