Instagram communicates your brand story in an authentic and intimate way, while still reaching a large audience. It has the potential to create an inspired community rather then a one-off customer. It not only shows you a brands purpose, but gives you an insight in to the personality of the person/brand and what they care about.

Instagram is an online mobile photo-sharing,
video-sharing, and
social networking service
that enables its users to take pictures and videos,
and share them either publicly or privately on the app,
as well as through a variety of other social networking platforms, such as Facebook, Twitter, Tumblr, and Flickr.
