This prompts some thoughts that the Notables project might best answer:
First, is there a useful overall list of the kinds of people who are notable, to expand upon the list that you started -- journalists, athletes, etc?
Second, what is the best higher level categorizations? At the moment, it is impossible to find "Notables" under categories or to imagine which category there it might fit under. Should there be a high level Notables category, under which there would be Athletes and Journalists, under which there would then be Notable Athletes, United States or American Notable Athletes, and Notable Athletes, Canada, or Canadian Notable Athletes?
Third, do you want all Canadian Notable Athletes in one destination category to which profiles would be attached, or do you want the profiles attached at the provincial level, so you would really have to look province by province to see what Canadian Notable Athletes have been categorized?
