Are they really "dating" sites if the purpose is just to get adopted as a male successor?

I think typically they would also marry the daughter of the current owner.

I can imagine the pitch to VCs: "It's Monster meets OkCupid!"

[snlacks]

Maybe you're onto something, OKCupid has a better track record as the method is actually based on some type of observable patterns. :)

[phaemon]

I think the motive is the exact opposite of 'ulterior'.
