I review when smth is exceptionally good or bad. But my point is not about how often you or I post reviews. It's about how often a place gets reviewed in general..... If you look at Candian locations, you will notice that on average, there are at least 1-2 reviews a day. The same goes for Tempe. Now look at Chicago, Guelph, and Tuscon. 1 review a week, if that. The places are simply not busy so they get reviewed less. In the case of Guelph, it's a whole of a lot less.
