I spent 3 hours over 3 agonizing evenings filling out the eHarmony.com profile thing and this is what I got back after 30 milliseconds of thought by the mainframe.
eHarmony is based upon a complex matching system developed through extensive testing of married individuals. One of the requirements for it to work successfully is for participants to fall into our rigorously defined profiles. If we aren’t able to match a user well using these profiles, the most considerate approach is to inform them early in the process.
We are so convinced of the importance of creating compatible matches to help people establish and enjoy happy, lasting relationships that we choose not to provide service rather than risk an uncertain match.
Unfortunately, we are not able to make our profiles work for you. Our matching system is not suitable for about 20% of potential users, so 1 in 5 people simply would not benefit from our service. We hope that you understand that we regret our inability to provide service for you at this time.
And their system seems to be broken… The FAQ says that I can change my profile to cast a wider net (ie, change the geographic area I’m willing to accept, religious beliefs, etc). But I don’t see the button they want me to push on the web site. :-( I wrote to them.
