The quote that got me was:
Specialized markets...they exist everywhere.
Other dating sites, he says, are just not for him: They're geared to "people who are more normal."
By the way, to readers who are keeping tabs with me: No, I have yet to succumb to joining an online dating service. Although, don't let me make you think that it's easy out in the "dating market." It can still be very rewarding (new people to meet) and disappointing (sometimes things have to end or never end up going anywhere).
