The "44 days" outlier (Grov) appeared in our snapshots on 12 unique dates spread across 47 calendar days, not continuously. Our methodology measured time between first and last appearance in the top 50, which collapses resubmissions into one window. That's a real limitation we should have flagged.
The raw data: Grov first appeared Dec 8, then clusters on Dec 17-22, Dec 29, and Jan 16-24. Big gaps in between. It wasn't sitting on the front page for 44 days straight — it kept reappearing.
We're updating the study to add a "continuous visibility" metric alongside the existing one. The core finding still holds (99% of Show HNs are gone within days, and the median post gets a single 30-min window), but the outlier framing was misleading.

Appreciate the pushback.
