E-mail worries me. Actually, its how we use it that bothers me the most. Think of email as little post-its left around for your friends, relatives and colleagues who must respond back to them with more post-its and you'll see the beginnings of a yellow brick road leading to an Oz where the wizard is none other than Adam Bosworth.
I have no problem with E-mail's original purpose of allowing people to passively communicate and remind each other of projects and grocery lists and stuff. But foregoing the meet-and-greet, face-to-face, in-person conversations for E-mail chat is another story.
For example, Netflix has basically allowed me to stop going to the movie theater unless its a must-see major blockbuster that really is worth the experience. That experience though, so often shared together with friends or family, has now become a lonely masturbatory affair in one's living room on a small flat screen and a worn-out couch with a permanent imprint of one's derrière.
Similarly, E-mail has made us loners (albeit very available loners), indifferent to the extreme of stepping out to knock on a friend's door when its so easy and convenient just to e-mail them. The impromptu get-together has become lost in the zany roads of the information superhighway. These days, we need video game consoles like the Wii to remind us to get a breath of fresh air and play outside for a change!
