I've gone "old school" (trying to connect to people in 'old fashion' ways) on many somewhat prolonged occasions and it doesn't work. It's a reflection of society not my particular grouping of friends.
I spent a year writing many handwritten letters. People loved receiving them but seldom, if ever, returned the favor. I try and try again to meet with my friends to catch up (ie, going for coffee). Almost never happens, and when it does it's a chore to actually set up. Instead, it has to be an 'event' and it should be 'social'. I text my friends and they respond rather quickly...because I know if I call, many times they don't answer.
Of course, all this means is that the LCD is either me or society.
I think it's a rational trend. Our direction has been towards more "omniscient/passive" forms of information, where you can update at your own pace, and others consume that information optionally. Doing this is cost-effective and allows people to prioritize their contacts by reading their feed occasionally, rather than by doing "pavement pounding" to make calls and arrange dates.
In doing this we miss out on some deeper conversations, but I think we gain on balance because it allows people to _choose_ which conversations they want to pursue. That's the key thing here - if you aren't feeling a benefit from socializing, you aren't motivated to do it. Which inevitably leads to the conclusion that most people are finding each other boring, even if they're friends...
I more than "lean" towards introversion, and this doesn't really frighten me; it makes me a bit sad, that's all. But I doubt it's a new observation. I suspect most people have always found most other people boring much of the time, even if they are friends. It's just more evident now because people have more alternatives for spending their time that fill a need for "socializing" without requiring direct in-person interaction.
