It’s an interesting move, as it shifts the service even further from her it started. In the beginning it was an image sharing app, that tended to focus on people creating “arty” effects via the inbuilt filters. That faded somewhat as the filters were toned down, but it still remained a crafted photo-centric service. But the net effect of this and the rapid growth of Instagram Stories has turned it into a general purpose visual communication and relationship maintenance tool.

Still, might make some verification work easier. One image is much easier to fake than 10.
