Fred Wilson, at a recent PandoMonthly, called Foursquare "Maps with people in them." Maybe if this were 2009 it would be. But I'm forced to disagree with the iconic venture capitalist. Foursquare is, or rather could be, much more. I view Foursquare as a combination of three core concepts: friend stream, explore and lists, which owe their existence to a powerful and highly developed API, although that has been both a blessing and a curse. This provides a foundation to Fousquare's potential second coming, if the company plays its cards right, and it involves maps, but not necessarily with people in them.
You can learn a lot about your company from usage behavior in Japan. Just like the Japanese language has a system for incorporating foreign words, when Japan latches onto particular Internet services like it did with Yahoo and Twitter, they become so important and widspread that they take on a trajectory all of their own.
I avoided Singapore for so many years. I had always seen it as a sleepy town with ridiculous gum laws. I felt there was no need for a regional hub for Asia when the countries in the region had such different market dynamics and culture. At the same time, I spent many years studying and working in China and traveling Asia, and I got tired of watching entrepreneurs use Chinese culture as a proxy for a business model, where translating a Web service to China was more important than starting from scratch and innovating a new user experience.
