From our experience doing the digital town halls that we've had at HuffPost Canada, what's been interesting is that the most engagement has come from an ability to talk directly to cabinet ministers—perhaps not the leaders who are in the spotlight, but people who hold considerable influence in cabinet, because the public generally doesn't have a chance to interact with them on those types of very specific issues.
I would ask that you consider that those types of specific topics become possible areas of focus so that people can focus down their questions. A lot of times the general leaders' debates are very broad, and there is only so much time to briefly touch on a topic before they jump on to something else.
