Discussions of the application of digital to democracy tend to get bogged down quite quickly in the (limited) merits and (extensive) risks of online voting. A more promising approach is to look at ways in which digital technologies can support and amplify democratic processes, more to do with deliberation and engagement than with quantification. This is still new territory, so experimental approaches still make good sense, but as this post brings out, there are now enough of those experiments around the world to start to group them and to see common opportunities and challenges.
