Researchers have found that friendships are more likely to last if both friends live near each other.
I'm using OkCupid, a free online-dating and friend-matching site. When I search for matches, OkCupid lets me filter the list of potential matches by proximity. But the closest proximity option is "within 25 miles of me". How can I search for matches who live within 5 miles of me?
NOTE: For non-US users, OkCupid's 5-mile and 10-mile proximity filters usually don't work as expected. Outside the US, these filters can't narrow down search results within cities.
