You couldn’t be more wrong. Your Canadian pride has outstripped your logic when contemplating this issue. There are 3 networks in the Bay Area of California, and SAN FRANCISCO, CA is the smallest of them. Unless you are actually in the city limits of SF, you are far more likely to be in the EAST BAY, CA network or especially the SILICON VALLEY, CA network. Overall, if you add up the three networks and divide by the total population, the Bay Area of California is far more represented on Facebook than is the singular WINNEPEG, MB network.

Overall, when looking at actual numbers and accounting for all possible networks in an area, Facebook seems more popular in major US regions than it is anywhere in Canada. The mistake you and others have made when looking at this is that Canadian networks seem to be much more spread out than the myriad of American networks that are often within 5 miles of each other.

In the case of Facebook, the proportion of Canadian participation FAR outstrips that of Americans to the point of there being more Facebookers in Winnipeg than in San Francisco. (again no source – sorry)

That’s the difference I wonder about.
