Silicon Valley has led the world in innovation and entrepreneurship because of its culture of information sharing and mentoring. No other region in the world is like it. But things are changing. In my travels to countries like India, China, and Chile, I've witnessed a noticeable evolution in entrepreneurial culture over the past five years. Networking groups are emerging, and entrepreneurs are becoming more open. One of the most impressive examples of this is in Campinas, Brazil-a small university town on the outskirts of Sao Paulo.
