Hacker News Reader

HN is also a moderated system, there's this guy called dang you may have heard of.

But he's not going around curating your reading lists, does he? That's the point.

In your own P2P Facebook, you'll be your own dang.

HN's algorithm for deciding what gets on the first page is not totally trivial. Is it published anywhere?

I think it's tweaked periodically, and unpublished to make manipulation harder.
