Based on http://paulgraham.com/ambitious.html I asked myself what would it take to build a Google-like search engine? What would change people's minds about using different search engine than Google and then it hit me out of the blue.
I would love to use nonprofit open-source search engine. That's why I built Sleio (http://www.sleio.com/) - a search engine that donates 100% of its profits to causes you love. It's powered by Google at the moment, but I believe it's a good start.
I am eager to hear ideas how to make this happen. Your feedback is very appreciated.
