Hacker News has a hidden superpower, and it isn't the front page. It's the comments.

That's where people quietly say "you have to watch this" , "read this book" , "just use this tool" . Then the thread sinks and the advice gets buried.

This week, three projects dug it back up.

📺 First: HackerTube

@karpathy built HackerTube: the videos HN commenters recommend to each other.

I liked it so much I turned the idea into a channel on DEV·TV , my retro TV for developers. Channel 15 HN PICKS now plays HN-recommended videos, each showing how many users recommended it.

📚 Then: HackerBooks

A day later, HackerBooks hit the HN front page: ~16.5k books that HN commenters brought up, from 2007 till now.

🛠️ Now: HackerTools
