Today, we base our developer products on open standards because interoperability is a critical element of user choice. What does this mean for Google Product Managers and Engineers? Simple: whenever possible, use existing open standards. If you are venturing into an area where open standards don't exist, create them. If existing standards aren't as good as they should be, work to improve them and make those improvements as simple and well documented as you can. Our top priorities should always be users and the industry at large and not just the good of Google, and you should work with standards committees to make our changes part of the accepted specification.
So as you are building your product or adding new features, stop and ask yourself: Would open sourcing this code promote the open Internet? Would it spur greater user, advertiser, and partner choice? Would it lead to greater competition and innovation? If so, then you should make it open source. And when you do, do it right; don't just push it over the wall into the public realm and forget about it. Make sure you have the resources to pay attention to the code and foster developer engagement.
So while having more personal information online can be quite beneficial to everyone, its uses should be guided by principles that are responsible, scalable, and flexible enough to grow and change with our industry. And unlike open technology, where our objective is to grow the Internet ecosystem, our approach to open information is to build trust with the individuals who engage within that ecosystem (users, partners, and customers). Trust is the most important currency online, so to build it we adhere to three principles of open information: value, transparency, and control.
