Yes. Heavily. But "back in the day" for me was between 1986 and 1993. I was already on the internet from 1989 and by sometime in 1994 it was pretty much all internet. I can't recall for certain but I think the last BBS I dialed into must have been no later than 1995 sometime.

Computers during that time... Commodore 64, Amigas (500, 2000, 3000) and a self-built Pentium 90 which ran the then-new Windows95 as its first and sole operating system. I'm proud to have never run DOS nor Windows 1-3.x
