In the comments section of a deep-Youtube Japanese synth music video, users shared personal life updates, or "checkpoints" when the algorithm would recommend the video.  

‍

These comments accumulated to the tune of hundreds before the video was removed by Youtube in 2021.

‍

This book contains a curated collection of 99 Checkpoints, along with two essays and an interview with Rebane2001, the user who archived the video before its unfortunate deletion by YouTube.
