Man is a social being. But not everyone likes the same things (obviously).
If there were a "meet-n-greet" of Orbinauts, would you attend?
Or a NASA event open to the public, no admission fee, and a chance to meet several members of the current and past astronaut corp, would you attend?
I met my wife while paying for gas at a conveinience store. If I were antisocial/introverted I probably wouldn't have flirted so much with her (dated 2 nights later, married 1 1/2 years later and just celebrated our 20th anniversary in October).
My daughter dumped one of her past boyfriends because he couldn't pull his head out of his, uhh, laptop. At the time of the BP oil spill he didn't know anything about it, and once he found out he couldn't understand what the big deal was.
Anyway, IMHO, this forum (and several like it) are a natural extensions or continuations of those BBSs that I had so much fun with in the 80's (mmm 300 baud modems). But there are several "brands" of social media that have done nothing but make people less social.
There are exceptions. As a member of a particular fraternity, we are obligated to look in and take care of the widows of members that have passed on. Several of them (mostly very elderly) have taken to facebook like a dog to a fire hydrant. Reconnecting to old (literally speaking) friends and family members that live all over the country.
My daughter on the other hand, knows that if I catch her staring at her lap at the dinner table too many times (particularly if we are eating out) she runs the risk of her phone being inoperable soon, or losing possesion of it for a while.
