OkCupid.com creates a unique online dating site environment by putting heavy emphasis on member participation. Matches are identified by your profile and your responses to a series of questions generated by other users. Each match question is made up of four parts: the question, the answers you’re willing to accept from your matches, a rating of how important the answer is to you, and an optional explanation of your response. The more questions you answer, the smarter OkCupid gets at recommending matches for you. It is free to use; paid options are available that include additional site features. While OkCupid is a free online dating site, users can pay (starting at $4.95 a month) to filter out people who are unattractive or overweight. An unusual, possibly controversial feature.
Age-based niches: These sites are for people of a specific age. Baby boomers are overwhelmingly turning to the web to find a mate. Sites like Match.com and POF.com offer members a chance to search specifically for the age group that interests you, but SeniorPeopleMeet.com and OurTime.com are the two largest sites designed specifically for the baby boomer market.
