From an interview with Richard Cheshire (AKA Cheshire Catalyst), a prominent phone phreaker, at H2K.

Why is Chinese food / restaurants so popular among hackers?
It’s a complicated structure … the thing with Chinese dinners is that everybody orders something. It’s a very large plate of that thing and you share it all around. You share resources!

I’ve never thought of my native cuisine as particularly hacker in nature, but I’d love to see a more detailed study/analysis of this for selfish reasons.
