Richard this is one of the biggest "myths" of "online dating" if you talk to anyone who has met their spouse through CatholicMatch or even another site they will tell you that the initial introduction happened online and all of the "dating" was in person. Some people are better at communicating online or over the phone and can do it longer before meeting in person but even in those cases you don't really "know" until you met in person and spend time together. I met my wife through CatholicMatch and helped create the site and I would NEVER tell anyone that online communication is better than in-person. But not everything in life is ideal and God can you even the less ideal to bring forth His plan if we cooperate.
I have to agree Brian - I think there are a great many pluses for on line dating in getting to know the person. Also being open to really what God wants and by being open to everyone who contacts you without preconceived notions. Not saying that chemistry is not important, it is extremely important but sometimes God may have someone in store that we would have clicked next, if we had not been open.
IRL dating we look for the chemistry immediately and chemistry although important is not the whole picture, only a piece of the pie. Through the forums and taking some time to initially interact provides one with a better view of the other, rather than meeting and if not initially connecting immediately, writing the person off.
Richard, CM has a great Catholic Community besides on line dating, where people come together to pray on the Teleconference Rosary Calls. We pray for Admin and the site, we pray for our CM members, that they find "the one" God is calling them for as well as their various intentions.
There are also events that helps one broaden their CM Community so that they can be a support network to each other. CM has much to offer that the other sites do not. Be open and reach out in various way that the fruits God has given through the channels of CM and you may be pleasantly surprised.
