I think it's a very exciting question, actually. I think the CBC is already experimenting somewhat in this regard. It always invites comments from its listeners and posts them on the web. It has a minimal policy of editorial interference with those posted comments. The problem is that they're not then interactive in a fundamental way. But it's designed its Canada.ca so that you can go out into another zone and then return back, so you identify different spaces where different rules are in play.
I would simply state that Mr. Stephen Ward, at the University of British Columbia's Sing Tao School of Journalism, has been fascinated by the blogging world and the new standards that are evolving in social communities. It seems to me that we aren't completely there yet, but there seem to be evolving protocols, much like the protocol in Wikipedia, where instead of objectivity, there are protocols with respect to balance and fairness in representation of views that seem to be emerging. Certainly my point would be that the CBC is one of these news organizations in a dialogue with its citizens, so it needs to be on the front line of researching and articulating what these evolving social standards are and when they are offended, so that we have a better system of ethical regulation in this country, more responsive to our needs as citizens.
