'Don't put ALL your eggs in one basket'.
This place is not the be-all or end-all to finding a good, faithful spouse. In fact, I would posit, it's more of a self-reverential catholic (small 'c') ghetto'd whine and cheese festival than it is a site for Catholic adults. It's a business, not a charity, and the developers who took the chance and developed the site are (rightfully) enjoying the profits of their labor. But, don't delude yourself that this is a non-commercial charity: it's a big, profitable, and successful business built on the dreams of lonely people with Catholic wallpaper to make it palatable to believers.
Lot of reasons to be here: common (well in theory) faith, expectations, etc. All nice in theory.
In reality: it's NO different from the other 2 major sites that advertise on TV. Same issues. People don't change just because the decorations are different; I've met folks from other sites who are also on here, and the profiles (and thus expectations?) were 180 degrees out of phase between the two sites.
So, why be here? As long as you take the gauzy stars out of your eyes...because finding a spouse is a numbers game. The more numbers you have in the barrel, yes, the more you have to toss out, but the greater the chance that you will find one you can live with. It's like going out to buy a new car...do you go to the lot with the 3 cars in front of the office, or do you head to the lot that seems to go on forever? Same thing here...the greater the population (and, when you combine brand M, brand E, and this place, you have extended your 'pool' a lot more comprehensively) the greater the chance you will find, if you are really serious rather than dithering around sounding pious and focused but in reality have not a single clue, your partner.
It's a numbers game. This is just one more place to increase the odds. Nothing more. You pays your money, you takes your chances.
