Overview
Accuracy: 0 exact matches, 33% theme match (10 out of 30 stories). Tuesday January 14 was dominated by Claude Cowork security disclosure (#1, 747pts, 330 comments) - a story we didn't predict but should have anticipated given the Cowork launch on Jan 12. The FBI raid on Washington Post reporter (#11, 909pts, 573 comments) was a major political surprise. Our predictions focused heavily on Apple-Google analysis and Simon Willison content that didn't materialize on this day.
MAJOR HIT: Cowork Security Theme (Different Angle)
Predicted #1: "Simon Willison's Deep Dive: Claude Cowork Security Implications"
Actual #1: "Claude Cowork exfiltrates files" (promptarmor.com, 747pts, 330 comments)
We predicted Cowork security analysis would dominate - it did! But from promptarmor.com with a security disclosure, not Simon Willison's analysis. The theme was exactly right: Cowork security concerns topped HN. MAJOR THEME MATCH - we correctly predicted AI agent security would dominate.
MAJOR SURPRISE: FBI Raid on Reporter at #11
Actual #11: "FBI raids Washington Post reporter's home" (theguardian.com, 909pts, 573 comments)
