Prediction vs Reality

Overview

Accuracy: 0 exact matches, 27% theme match (8 out of 30 stories). Monday January 13 was dominated by major unexpected news: Scott Adams' death (#3, 1020pts with 1587 comments), Bandcamp's AI music ban (#2, 883pts with 659 comments), and continued Chromium JpegXL merge discussion (#12, 435pts). Our predictions heavily focused on macOS Tahoe follow-ups and Microsoft layoffs that didn't materialize. Key lesson: Obituary news and platform policy changes can dominate unexpectedly. The Tulip Creative Computer at #1 (237pts) was a quirky hardware project we missed entirely.

MAJOR SURPRISE: Scott Adams Death at #3

Actual #3: "Scott Adams has died" (youtube.com, 1020pts, 1587 comments)

Actual #25: "Scott Adams has died" (usatoday.com, 420pts, 3 comments)

The Dilbert creator's death from prostate cancer dominated HN discussion with over 1500 comments on the main thread. We had no way to predict this. This is the third time in recent weeks that an obituary has generated massive HN engagement.

Lesson: Obituaries of tech-adjacent figures can hit #1 with 1000+ points. Cannot be predicted but should be acknowledged as a category.
