Every single person who uses the Internet is already engaged with the network, what they are not in most circumstances is actively engaged.

Active engagement is the next step in the development of the web. Users will become increasingly involved in carrying out an action or process in order to reach the content they desire and engage with it, this is Active Engagement.

Active Engagement can be for example implementing and RSS feed into your net vibes account, defining the parameters around which that RSS feed will display and then visiting the content that is flagged up for them.

An actively engaged audience is more connected to the network and it means more to them than a passive engagement.

These theories have more development to go but this is the basis.
