Well, let's say that those factors are the most immediate ones for attraction. This doesn't translate much to "the chapel".

I've been thinking a bit about online dating (heh) and dating in general. My latest idea is that a successful match is not much a matter of state, but rather a matter of process. Two people might be well suited for each other but to get beyond the most superficial attraction you need time spent together and meaningful experiences.

They could create a dating website that encourages "matches" to go through a set of random activities, that would be fun (and, I guess, successful).
