"Seriously though, how do you usefully and efficiently keep in touch with more than 1 person via telephone? I can't even imagine it working."
In response to that I'd say think about what social life was like before the very recent invention of online social networks. There is no end to the amount of complex tasks that were arranged long before anything like social media existed, and long before anything as enabling as the telephone existed. The fact that someone would find it difficult to imagine a scenario without facebook, twitter etc. shows how disconnected from the abundant alternatives we have become.
You also have to understand that I am juuuuuust that age where I've used message boards and MSN more than the telephone in that time of being a teenager when you learn how to socialize with people.
Plus I was always a geek so that goes double for me. So, essentially, I never really learned how to use the phone effectively.
