Might I respond first?
I think you have a direct line into the CBC, and they're compelled to listen to what you say. When they're censoring their own blogs and when dialogue is taking place on Facebook and on independent websites because CBC doesn't want criticism, it becomes much harder for us to influence events. I would personally like to see your committee ask CBC why it censors its blog sites. I can't think of an explanation as to why that is good and appropriate practice for a crown corporation in a democracy.
