OkCupid is a free friendship, dating and social networking website that features member-created quizzes and multiple-choice questions. The site supports multiple modes of communication, including instant messages and emails. OkCupid was listed in Time magazine's 2007 Top 10 dating sites. The site is part of the "Match Developing" unit of IAC/InteractiveCorp's Match division.
OkCupid facilitates friendships as well as romantic relationships. OkCupid claimed 3.5 million active users as of September 2010. According to Compete.com, the website attracted 1.3 million unique visitors in February 2011.
The site used to have a highly active journal/blogging community as well. Journals are not available to new members and the feature is now "retired." Members have the option of saving favorite user profiles, which display the favorited person's responses to questions and profile updates on the member's front page.
Any adult may join the site and all users may communicate with others via private messages or an instant messaging "chat" function. A-List (paying) members see no advertising and have more filtering options and preferential placement in an "A-List Matches" section of search results. A-list members can also browse openly while choosing whether or not their profile is displayed to those they visited.
OkTrends, the official blog of OkCupid, presents statistical observations from OkCupid user interactions, to explore data from the online dating world. As of September 2013 the most recent entry on the blog is April 19th, 2011.
To generate matches, OkCupid applies data generated by users' activities on the site, as well as their answers to questions. When answering a question, a user indicates his or her own answer, the answers he or she would accept from partners, and the level of importance he or she places on the question. The results of these questions can be made public. OkCupid describes in detail the algorithm used to calculate match percentages. The site notifies a user if someone rates them 4 or 5 stars.
Attractiveness and match results
Users who receive high ratings may be notified by email that they are in the "top half of OkCupid's most attractive users" and "will now see more attractive people in [their] match results". The email also reads "And, no, we didn't just send this email to everyone on OkCupid. Go ask an ugly friend and see".
OkCupid was owned by Humor Rainbow, Inc. OkCupid’s founders (Chris Coyne, Christian Rudder, Sam Yagan, and Max Krohn) were students at Harvard University when they gained recognition for their creation of TheSpark and, later, SparkNotes. Among other things, TheSpark.com featured a number of humorous self-quizzes and personality tests, including the four-variable Myers-Briggs style Match Test. SparkMatch debuted as a beta experiment of allowing registered users who had taken the Match Test to search for and contact each other based on their Match Test types. The popularity of SparkMatch took off and it was launched as its own site, later renamed OkCupid. The current OkCupid Dating Persona Test is still largely identical, in question and text blurb content and order, to the original Match Test. In 2001, they sold SparkNotes to Barnes & Noble, and began work on OkCupid.
Since August 2009, OkCupid has included an "A-list" account option that provides additional services for a monthly fee.
In February 2011, OkCupid was acquired by IAC/InterActiveCorp, operators of Match.com, for $50 million. Editorial posts from 2010 by an OkCupid founder criticizing Match.com and pay-dating as exploiting users and as "fundamentally broken" were removed from the OkCupid blog at the same time. In a press response OkCupid's CEO commented that the removal was voluntary.
On March 31, 2014 any user accessing OKCupid from Firefox was presented with a message asking users to boycott the internet browser due to new CEO Brendan Eich's support of Proposition 8. Users were asked instead to consider other browsers. On April 2, 2014 the dating site revoked the Firefox ban.
