No matter what type of web site or application you’re building, social interaction among the people who use it will be key to its success. They will talk about it, invite their friends, complain, sing its high praises, and dissect it in countless ways. With the right design strategy you can use this social interaction to get people signing up, coming back regularly, and bringing others into the fold. With tons of examples from real-world interfaces and a touch of the underlying social psychology theory, Joshua Porter shows you how to design your next great social web application.
