my mother-in-law apparently made some, looking-for-a-wife-for-my-hard-working-son, post in an fb group and got "a lot" of replies and interactions, and now her son is texting with several girls (all out of state)

she feels like she's struck gold, and comes to with the idea of building a dating site that is geared for our guys (not in those words)

I have a lot of misgivings about something like this, but am wondering if it could be done right. it just seems like any dating site is going to be naturally void of the things that make a strong relationship/marriage, but is it just a longer fishing line in a huge sea of fish?
