As far as I know there was only the alt.surfing newsgroup that started in 1990. Of course, that was the NNTP protocol, and not HTTP. One of the first functional web browsers (leveraging HTTP) was Mosaic, released in 1993. Believe the first instantiation of https://www.surfermag.com was in 1996, which included the "Monster Bulletin Board," and which the erBB was partially named after (distinction of SURFer and SURFing mags).Was there a er-mag dial-up BB in the 80's? I'm trying to remember.
Some of you youngsters maybe don't know this, but your computer modem needed to phone a bulletin board in order to get "on line".
