I don't like eHarmony's business model but it's their right to have that model. It's a niche buisness... just like Gay.com, BMB, and even J-Date. It just happens that their niche is huge and doesn't cater to me... and I would rather use a service that wants me as a client than one that is forced to serve me. If I was vegetarian I wouldn't feel that steakhouses should have vegetarian options. If the steakhouse has them... good for them... but why would a vegetarian want to go to a steakhouse. Why would a gay want to use a dating site that probably thinks they shouldn't be allowed to get married; that the extent of their relationship is based on lust not love.
You don't take a Ducati motorcycle to be fixed by a Honda Accord mechanic.... that's all I'm saying.
