I wasn't all that tech savvy but I was using the internet in 1985 when I was a university student. Oh, right, it wasn't called "the internet" and we used bang addresses for email and rcp instead of scp to copy files between hosts because security was physical locks on the room with the VAX in it, but it was continuous with what is today called the internet.

I was using internet email and Usenet in 1985. I wasn't "tech savvy" - I coded, but I didn't know much about the internet or email. I got access through a UK BBS system called CIX (Compulink Information eXchange).

I first came across Usenet through my employment with Olivetti. They were selling AT&T Unix minis at the time, so we had a Usenet feed via AT&Ts office on the other side of the city. Two updates daily, I think.

[Edit] For home access to CIX, I was using a 1400-baud acoustic coupler, which I had "liberated" from the basement of a former employer. Bandwidth mattered in those days - you could DoS someone by sending them ten pages of text.
