Most of the young people in the mobile phone generation have fewer social skills than those who grew up in a more balanced society, so they have to resort to the Internet to find a spouse. I know a woman who has only met social misfits and weirdos on the Internet dating sites. If young people don't volunteer, get involved with clubs, church, university social gatherings, or even go to the local pub or discotheque, their chances of meeting a decent partner are somewhat limited.
I think that's a rather warped impression.
People in the mobile generation grew up with that communication medium being an integral part of society, they never lived in a world without the internet and communicating online is a natural part of their lives. It's not a matter of "resorting to the internet", rather they are already socializing on the internet, they are already interacting and meeting new people, "online" is a seamless part of society these days, it's only natural that some will form romantic relationships with people they met in this way.
I know a woman that has only met social misfits and weirdos in the "real world" so what's your point? The sort of people one meets is more often down to the sort of traits they are attracted to and the way that they present themselves. The internet is no different than anywhere else, it's a method of communication, nothing more. It's not 1998 anymore, the internet is not dominated by geeks and weirdos, everyone is using it now. Volunteering, clubs, church, university, social gatherings, all those things you mention are still around, although most also have an online presence. I'm not really a user of traditional social media but if you can hold your nose and hop onto Facebook you'll find countless groups for all of these things. No longer are we limited to the dating pool available in whatever little town we live in or reliant on going away to school in the big city to meet a partner, people can meet and interact with people all over the world. Romance aside, the internet has enabled me to meet loads of friends who share my interests, some of the more unusual ones I thought for a long time I was the only one.
Frankly, and I mean no disrespect and am not exactly young myself, but this sounds like a classic example of an older generation not understanding the younger generations and the evolutions in society that have taken place, lamenting these young whippersnappers and their newfangled technology, slang, music and everything else that is not as good as things were back in their day when life was hard and they walked 20 miles through the snow up-hill both ways to get to school. This cycle is as old as time, in a handful of decades the people who are coming of age now are going to be moaning about all the silly stuff kids are doing and how much worse everything is just like the older generations are doing today.
