Is technology really bringing us together?

Now don't get me wrong. I have really enjoyed my blogging experience. But I can't help but question, in a classroom setting, does blogging unify the class, or separate it? Let me qualify that question. We are in an age where communication is easier than it has ever been. We can follow the news in myriad mediums. We can send and recieve emails rather than wait for days or months to receive snail mail. But it seems to me that technology leads to a downgrade in communication rather than an upgrade. We spend time every week sitting at a computer communicating in writing precisely so we don't have to sit down in person with people who walk around all day on our same campus! We say, "isn't this convenient that I can get all the benefits of talking to Danielle without ever really having to talk to Danielle?" Now I can go online and grocery shop, having my groceries delivered to my house, so that I never have to interact with the other shoppers in my community. All of my entertainment needs can be met from the comfort of my own house via satelite, withouth the discomfort of interpersonal interaction in, say, a theatre or community dinner. It seems that technology is doing more to separate us from the world and from eachother than it is doing to unite us. What do you think?
