I like modern digital communications, though they do have their drawbacks when used for interpersonal messaging. The lack of voice inflection and body language, mentioned earlier above, places the responsibility for conveying the message meaning solely upon the written words alone. And many people today do not have very sophisticated writing skills, at least not those individuals coming out of the current US education system.
There was a time when people had "pen pals" with whom they corresponded by paper mail over great distances, sometimes leading to their meeting in person, or sometimes never. I see computerized communications in much the same way, just a faster and paperless form of it. Plus when you post to blogs & forums, or blast an e-mail, you can have many readers at once, rather than just one. But the principle to me is the same, and really quite old.
Nor does it lead me to substitute virtual friends for real ones. On the contrary, I use the one to increase the other, to expand the scope and locale of people I meet in person. And when we meet I communicate all over them. paulflexes and a few others right here know that. LOL! And I'm as garrulous on the phone as I am in writing -- just ask meninlove.
So I dunno, modern means of communication has increased my daily communicating utilizing every means, not reduced or narrowed it, nor has it damaged my skills. And my circle of in-person friends has increased since I started going online in the 1980s, not decreased, so I'm certainly not a reclusive shut-in as a result of it (though my friendship numbers also got a big boost due to my coming out gay at the same time).
