August 20, in online dating Tags: online dating , plenty of fish. I used Plenty Of Fish, which currently is the most widely used site. The search was done using a central Toronto postal code and was done over four different evenings at slightly different times, all of which seemed to exhibit a pretty similar pattern. As to the age splits I chose, they seem reasonable. Any choice of groupings is at least somewhat arbitrary and could probably be criticized, but short of doing a separate count for each and every age this seemed like a good choice.
