To give you some stats, in Canada, nearly 1.5 million people, or approximately 10% of Canada's mobile daily active users, click on an instant article every day, and more than seven million people, or more than 40% of Canada's 17 million daily active people on Facebook, engage with publisher content by clicking on the link that takes them directly to their website.
With respect to your other question, sir, I believe you are referring to references with regard to a filter bubble, or an echo chamber, as I've read it described. There is empirical research, which is peer reviewed, published on this. It shows that, in fact, when you look at the numbers, people are actually exposed to more differing views online, it turns out, than they would be in their day-to-day lives. This, perhaps intuitively, is interesting, because in our day-to-day lives we're going to go and meet with the same few people every day, whereas on Facebook, as an example, you connect with friends from high school, friends from university, friends from work, and neighbours.
Our CEO Sheryl Sandberg has described these people as both strong and weak ties. In fact, you will likely see much more diverse views expressed on Facebook than you would in the past when you would presumably interact with five to 10 people a day or consume your content from one particular television station or newspaper.
