Social Network Aggregation is the process of collecting content from multiple social network services, such as MySpace or Facebook. The task is often performed by a social network aggregator, which pulls together information into a single location, or helps a user consolidate multiple social networking profiles into one profile. Various aggregation services provide tools or widgets to allow users to consolidate messages, track friends, combine bookmarks, search across multiple social networking sites, read RSS feeds for multiple social networks, see when their name is mentioned on various sites, access their profiles from a single interface, provide "lifestreams", etc. (Wikipedia)

The Social Networking Aggregation market is as large as the increase in social networking market itself.  I predict that social networks will increase 20-30% per year over the next 5 years.  You will see social networks springing up in your neighborhoods, communities, housing projects, businesses, civic and government centers, libraries, and health care facilities, just to mention a few. 

For over a century, people have been moving away from villages and neighborhoods, to more individual, yet networked, households.  This has occurred due to education, job, transportation, and family transitions.  People however, still need the social bonding, mutual aid, identity, and a sense of belonging to family and community. Hence the migration to social networks and the use of the mobile telephones and Internet tools, i.e., email, streaming audio, video, images, instant messenger, and text messing (twitter): think of this as an online, or outdoor vs. indoor networking; an anywhere-everywhere-anytime phenomenon. 

This movement to networked societies has profound implications for how people mobilize and influence governments and relate to each other.  This is very important in democratic societies.  Think about this, what we are seeing on the Internet and through these social networking sites is a change in the way people communicate, promote ideas, and develop relationships all over the world.  Democracies are heavily in the business of dealing with the aggregated demands of their citizenries. 

 
This is the main reason for social network aggregation: the ability to control information as you look at the big picture.  Not only will you be able to control profiles, between social groups, you will be able to manage and market to demographic interest groups because you will captured the very nature of people by the information you can produce from this information.   Think about it, as people explain their likes and dislikes, wants, and desires with billions of other people, social network aggregation becomes a marketers dream come true.    

To expand on Social aggregation, think in terms of multilevel aggregation with local and regional groups, and to some extent, electronic citizenship can merely replicate communication and information diffusion.  Think of this: people are exposed to new information about products or services, and the early adopters or sneezers (Seth Godin's wording, ‘The Purple Cow’) spread the word by “word of mouse” or “word of content”. 

These aggregation engines will carry more data than just profiles; they will carry information about mass societal trends, civic matters, interpersonal relations, community issues, and demographic data both commercial and governmental.  So in a nut shell, you will be able to determine the interplay between Internet use and other more physical forms of personal involvement and participation with other people globally.
