How do you create?
When and what do you post? What meta-data do you include (location, caption, hashtags) and how frequently do you include it?
How do you consume?
Do you use the explore tab, and if so, how frequently? Do you browse hashtags? Locations? Strangers' profiles?
What are the contours of your Insta-graph?
Who do you follow? How does your Insta-graph compare to your other graphs? When do you decide to follow someone? Do you Insta-stalk?
What do you wish you could do on Instagram?
Follow places? Follow hashtags? Where would that content show up? Would you want it to work the same way as following a person? Would all posts about that location show up in your main stream? In notifications? In the explore tab?
