I (ironically, depending your penchant) used an AI judge to score every top HN post and its top comments all the way back to 2010 (over 300,000 individual judgments!), and created a nice interface with the historic charts.
The scoring is off of how much disgruntled AI pessimism the post and top comments show. You can use that score to either only show (in Doom Only mode) or hide (in calm mode) all the doom static.
This is part joke and partly to answer my own curiosity about how real my feeling that the comments and posts have grown increasingly overbearingly negative towards and focused on the worst of what results from AI in the past year.
The trends is stark. My intuition was reinforced by the analysis; disgruntled pessimism about AI is at an all time high in the last few weeks and on track to continue doubling annually since ChatGPT released.
Historic charts are at bottom of the page.
HN archive nostalgia that's fun to browse but mostly a novelty.
Runs 22GB of HN history entirely in-browser using lazy-loaded SQLite shards over WebAssembly.
Client-side sorting and true post ages for Hacker News, but the store listing is unavailable.
Twenty years of HN topics clustered and charted—see AI overtake startups.
You can scan decades of HN culture at a glance — the site lists 'epic' threads with sortable metrics (comments, points, linked/backlinked counts) and year filters, which makes recurring Ask HN threads and news spikes obvious. The UI is minimal and readable, but the product feels like an aggregator rather than analysis: show your grouping methodology, add CSV/JSON export or an API, and this would move from 'handy dashboard' to research tool.
60 years of metal data with regional breakdowns, but it's a visualization site without downloadable datasets or API.
