Here’s a working definition I used during today’s presentation at the 2013 Participatory Budgeting Conference:

Digital Engagement

The use of information and communications technologies to support, enhance or extend public participation and civic engagement processes.

Another one comes to us via Steph Gray:

Digital Engagement uses digital tools and channels to find, listen to and mobilise a community around an issue, maybe getting them to talk about it, give you their views or take action in pursuit of a cause they care about.

Any others? Thoughts?
