The site uses the numerical values to calculate “friend”, “enemy”, and “match” percentages between any two members of the site based on how many answered questions those two users have in common with higher intersections supposedly producing more accurate percentages.
There is a very active journaling/blogging community on OkCupid as well. Members have the option of saving favorite users’ profiles and then “stalking” them, which allows them to view all of their new journal entries, as well as comments on others’ entries.
