People are busy; they all have something on their plates already. How can we grab their interests and persuade them to join us?
Remember that some engagement is better than none, and think early and often about your target audience. How can you engineer an array of entry-points and pathways to participation for your community? Where are the opportunities for light-touch engagement that is potentially powerful in itself and also a possible gateway into deeper involvement? Make acting easy, so your users can co-produce your civic and political engagement.
