We got internet when I was around 7, Prodigy, 1994 or 1995. I never used it because there wasn't shit for a kid to do. We had Prodigy until like 2002. My old man signed a long contract with them, it was a good deal, but wouldn't you know, right after he signed it, cable internet became available. And you can bet 14 year old me wore him down, it was not a want, but a need.
Living in a university town with a much older, tech-savvy brother meant I first used the internet in 1990 at the age of 13. I used the internet before pretty much anyone I know other than my brother, but I was on MU*s and Usenet like it was home and then I discovered IRC...
I'm not saying I was smart, just lucky. In fact, I was pretty stupid about the internet. I remember seeing an early website in 1993 maybe and saying something like, "it's cool, but it will never replace Gopher."
