Description
We took the top 3 HN stories every day since October 2006 (~21K stories total), ran topic clustering on them, and visualized how topics rise and fall over time.You can zoom into any period - some patterns are surprisingly clear (AI overtaking startup culture as HN's top topic, crypto's rise and fall, remote work spiking with COVID).Happy to answer questions about the methodology.

Could you build this?
Yes Scraping Hacker News archives via the public Firebase/Algolia API, running standard topic clustering (e.g., BERTopic or embeddings), and rendering an interactive timeline chart is well within vibe-coding scope.

Feature requests: Reverse-lookup stories by individual story to find categories, Browse from story outward to see classification and related stories, Improve query performance for public traffic
