There ARE start-ups designed to help the third world. I know of a few off-hand. Find them, link to them, start up a discussion. Do NOT spam this place. This is a place for programmers and hackers to discuss things they find interesting. That's kept it at a pretty high signal-to-noise ratio, even though that's slipping.
"The things of real value in this world are not monetary."
D'you know what? I'll treat you seriously here, if only to completely disagree. Money is a method of exchanging your ability for somebody else's. It's a bond between people when it's used right. You pay me to do what I do best, I pay you in return. It brings us together when we make a transaction. And so, when I'm making money, I know that I'm creating something of worth to people. And when I spend money, I spend it to improve life around me. Sound selfish? Sure. But my spending money gives somebody else money, and it lets them improve the world in their own little way. Everybody benefits.
We could debate this all day, and it would make for a nice little topic of its own. But you didn't start this thread for that. You started this thread either to gain karma or to distract people from actual HN-related threads, and you did it in the laziest way possible: by linking to a Google search for a generic term. No news article, even. That is NOT what this site needs.
There's a whole big wide Intertube out there. Plenty of places to discuss politics and social justice. whalliburton, do you have a technical or entrepreneurial insight to share about this?
