Hehe, love the links. Don't tell me you were using the internet way back then!
Well, this topic has gone totally off, but oh well. The guy hasn't answered my question yet.
I was introduced to various prequels to what we now know as 'the internet' at age 10 in ~1983.
(Yes, if you read your internet history, during the same time TCP/IP became a popular packet switching protocol)
My step-father was civilian contractor for the Air Force, and a division he worked with was highly interested in packet switching networks for communication.
Though I never saw the terminals or communication he used, the stories of magicly being able to type a letter and have someone reply to it in less than one day at age 10 was fascinating.
My first usage of the 'internet', at the time Usenet, was when my mom worked a computer store that sold to local businesses and schools.
(That was also when I played my first graphic adventure game, Sierra's King's Quest. As you can tell, gaming pretty much stuck.)
