How Many People Online Care about Causes?

In my last post, I identified four groups of cause-oriented individuals, including a pair of newcomers called the Cause Amplifiers.  I defined them as:

Cause Amplifiers
Traditionally, organizations have been responsible for amplifying a cause mostly using broadcast means. In the Interconnected Age, individuals are armed with ever-increasing amount of tools to create, modify, and disseminate the message, frequently on their own initiative.

You can account for this new pair by recognizing two more categories:

Connected – As proud members of the Interconnected Age, they maintain an active online presence, building and reinforcing a network of strong and weak ties. They amplify causes through dynamic signals they transmit via Twitter, Facebook, blog posts, and other social media platforms.

Creative – These individuals go beyond dynamic signals and lead the creation of websites, online campaigns, new alliances, or other innovations. Often, they have no formal ties to organizations normally associated with the cause and bring new, innovative solutions to amplifying the message.

Now that we have identified a new group of cause-oriented people, I have a simple question for you to consider:

How many people fit into the Cause Amplifiers category?
