When I look at the history there is a clear pattern: - Match.com solved it by starting in 1995 and working really hard. - eHarmony solved it by attracting the christian crowd with endorsements by pat roberson and great offline marketing. - plentyoffish solved it with a great brand name, and using the "free forever" look, feel, and marketing. - OKcupid solved it by creating tons of questionnaires that were fun and interesting. - AshleyMadison solved it by targeting the infidelity niche. - AdultFriendfinder solved it by marketing to suckers on gaming and porn sites. The pattern is clear. There is no pattern.
