Wow, I wish we lived near each other because I feel the exact same way.
The article you mention sounds akin to dating or matchmaking.
I agree that you have to get offline and out in person to meet people. I love parks for that reason. Now that my daughter is playing with other kids, I take her lead and can strike up a convo with the mom/caregiver.
The virtual world has helped me via meetup. I found a local moms group that has been wonderful. The great thing is the playdates are listed on meetup so there is something to do about 3 times a week.
The downfall--and the onus is on me--is that like most of the world, these moms are all on Facebook and are more in touch that way.
I, however, am "old-school," and can't stomach Facebook. To me, it's just another virtual way out. Plus, I have no desire to get in touch with high school people.
Anyway, I'd ignore the immature article you read. It sounds like the woman is in her 20s and single?
Head to the park, meetup or if you're kid(s) are school-aged, volunteer.
As for people looking at their cell phones, it's unfortunate but here to stay. Hold your head high and put yours on vibrate :-)
Good luck.
