"Social interface design is a new field. Much has been written about usability and interactive design, but still not a lot on social interface design. It is an intersection of various fields: interface design, sociology and psychology, and as such it requires more than just an understanding of usability and design; it requires an understanding of human behavior and interaction. Using concepts from these other fields help you make interfaces that aren’t just easy to use, but that steer your community in the intended direction." - Onur Kabadayi from Bookmarklet
