The author, Craig Hockenberry, reflects on the shutdown of Twitterrific, an app he developed, due to Twitter's API changes. He compares the decline of the app to his mother's passing, noting that while his mother's death was dignified, the app's shutdown was not. Hockenberry expresses frustration and disappointment with the way Twitter handled the situation. He also looks to the future, considering the potential of ActivityPub and the development of a universal timeline.
