From the website:
Viewfinder is a multimedia discussion board which uses images and video to help address the natural bias towards text in the online engagement arena. By using video to introduce and engage users Viewfinder is naturally suited to reaching a new audience for Council consultation.
New mapping features makes it easy to navigate and find content based on location. The use of community moderators means you can share moderation and facilitation with citizens making Viewfinder a more engaging community resource.
Viewfinder can be seen as a standalone project or as part of a wider process such as Participatory Budgeting.
