If you actually have the ability to make great matches, matches so good you are concerned you will lose two customers, you should be running a matchmaking service and not a dating website.
Not everything has to be a gimmick, right?
You used to see ads for them in Skymall.
My role here was writing snarky comments in Skymall catalogs to unwind on my Friday night redeye flights home. (I used to fly a lot for work)
Always sort of ethereal looking hot 40'sish blonde women. Implicitly promising you'll be able to date and marry one of those (but of course the hot 40's lady is the matchmaker).
They sort of similarly implicitly promised you could meet and marry a doctor or exec or something.
Also - the ads were never targeted at women.
