Hacker Smacker by Samuel Clay

Hacker Smacker adds friend/foe functionality to Hacker News, inspired by Slashdot's classic system.

Three small orbs appear next to every author's name on HN. Click to mark someone as a friend (highlighted in green) or a foe (marked in red). Neutral authors stay unmarked.

The real power is friend-of-a-friend (FoaF): if your friends also use Hacker Smacker, you'll see their friends and foes too. This helps you quickly spot quality commenters when scanning long threads.

Features:
- Friend or foe any author with one click
- See friend-of-a-friend and foe-of-a-friend indicators
- Works on all Hacker News pages
- Profile pages at hackersmacker.org showing your network
- Open source: github.com/samuelclay/hackersmacker

Privacy: Hacker Smacker only collects your HN username and your friend/foe ratings. No browsing data is tracked, nothing is sold, no ads.
