There’s a little over one million people living in Calgary, the city where I live, and according to Facebook there’s 121,519 people in the Calgary, AB network. If that statistic is correct – and it’s not just people who once lived here or something similar – that has to be the highest level I’ve ever seen of a population using the same online service. 12% of a major city all signed up for the same thing? That’s crazy when you think about the numbers, especially when you factor out the people not likely to use Facebook at this point in time (perhaps under age 10, over age 50). What’s the Facebook penetration like in your city as compared to the population?
