Importing the Hacker News Interest Graph by Max De Marzi.
From the post:
Graphs are everywhere. Think about the computer networks that allow you to read this sentence, the road or train networks that get you to work, the social network that surrounds you and the interest graph that holds your attention. Everywhere you look, graphs. If you manage to look somewhere and you don’t see a graph, then you may be looking at an opportunity to build one. Today we are going to do just that. We are going to make use of the new Neo4j Import tool to build a graph of the things that interest Hacker News.
The basic premise of Hacker News is that people post a link to a Story, people read it, and comment on what they read and the comments of other people. We could try to extract a Social Graph of people who interact with each other, but that wouldn’t be super helpful. Want to know the latest comment Patio11 made? You’ll have to find their profile and the threads they participated in. Unlike Facebook, Twitter or other social networks, Hacker News is an open forum.

A good starting point if you want to build a graph of Hacker News.
Enjoy!
