That's a great answer. The question was an attempt to see what's entertaining but not valuable, and what's so unique that there's no good substitute for. For instance, there are other web based email clients (not as good as gmail) but there's no other community I've found as great as HN. Since I'm sort of technologically isolated, the community here is a godsend that's the most stimulating entertainment I get outside of my wife and kids.
