Jonathan Zittrain defines Generativity in the following manner:

“Generativity is a system’s capacity to produce unanticipated change through unfiltered contributions from broad and varied audiences”

Jonathan Zittrain, The Future of the Internet and How to Stop It

In reality, this description somewhat defines the nature of a social networking sites. If you look at social networking sites today, users are able to participate in 3 ways, all of which contribute to the generative nature of a social network: Users are able to:

1. Generate self identifying content (their profile, blog, homepage)
2. Generate and consume bi-directional content (messaging, statuses)
3. Generate and consume multi-directional content (groups, discussion boards, forums)

These three methods of participation allow the internet and social networking sites to grow at the staggering rate they are today. However, as these sites grow, keeping the content organized so that it remains relevant and meaningful to the user, becomes increasingly difficult. This issue is more prominent in the third method, as users are able to impact the entire network in a single instance.

Take for example the Groups feature. A single user can create a group made available to the entire network. That’s fine. But what happens when multiple users create the same group? An overlap occurs, and what should have been a single meaningful group, now becomes one group of many just like it.

Today, I joined my University of Wisconsin – Madison group as I am a recent alumni. There were about 3-4 identical groups? Do I join them all? The same scenario applied to many of the groups I wanted to join.

The generative nature of social networks allow for more noise, and enables users to disrupt the very social graph they create, making the networks more complex and less meaningful. Other people recognize the growing occurrence of this noise, and ironically enough, have used the same generative nature of social networks to maintain strong connections, content, and a healthy social graph (see Triiibes).

About six weeks ago, I joined Seth Godin’s social network called Triiibes (which he created using a white-box social network: Ning). The network was only made available to those that made an early purchase for his new book. As a result, the content and communication in the network is much stronger and meaningful then I’ve seen on any other network.

As social networks grow, they must look to sites like Wikipedia for guidance. They must learn how to keep the network connected using only meaningful and unique data points.

(Jonathan Zittrain’s book is a good read for anyone interested in technology and communications, and their inevitable effects on society)
