This page answers “what surfaced more recently?”: videos are sorted by their latest Hacker News mention year. For a different question—“which talks have the most distinct recommenders?”—use the topic's Best Talks list when at least 20 talks are available. This topic has 16 cataloged talks. Its average per-video recommender count is 2.3; neither this metric nor recency represents YouTube views or a quality rating.

Topic labels follow the published taxonomy and may overlap. Use the filters to narrow by format, learning level, catalog shelf life, or how many distinct months a video received recommendations. Open a video record to compare it with same-topic videos and inspect its underlying HN context.
