I agree with everything Ellen's saying in this post:
How the web is changing certain social exchanges
The personal back and forth is what makes it all worthwhile, in my opinion. I even get annoyed at friends who overuse email instead of the phone, because even email is slightly less personal. I love actually seeing and talking to people. I am a social creature. As are many of us. Why do we fight it so?
Maybe I'm a young dinosaur, heh.
