As best as I can do with screenshots & printing to PDF to horizontally represent the vertical scroll of 41 photos in my Instagram feed this morning.

The Ordering of Instagram’s Algorithm: a Case Study (Not Really a Case Study)

A look at 41 photos in my feed this morning, but in what order?

At 8:40am, Sept. 20th, 2016, I checked my Instagram feed. We all know Instagram’s changed how it presents photos to you this year, moving away from the ol’ reliable chronological, to an algorithmic secret-sauce that leans heavily on popularity, shareableness, and the capacity for Instagram to upsell.

This morning, I thought I’d write down the sequence of images in my feed (poorly represented by the PDF contact sheet, above) just to see how much they differed from the old, “traveling back in time” method.

Here’s the 41 images above, in the sequence they were presented, showing the time they were originally posted, and linking to the original post:
