(might have some dates wrong)I was also on mIRC and downloading from newsgroups regularly.
I think many ISP's would give you guides about using email/newsgroups back then as those services were considered required for an ISP. TUCOWS was super popular for this newfangled WinSOCK software (TUCOWS stands for The Ultimate Collection Of WinSOCK Software). I remember testing how fast the first consumer cable internet connections were by downloading from them.
You are right for most people that stuff was probably obscure.
There was no such thing as a OS-monoculture.
