I did interact with a BBS site or two, but then got caught up in the AOL wave. I used their platform, Geocities, and a few other chat sites. Once ditching AOL around 1999 I ended up on a local forum we used for electronic music, and then in 2003 made my way to a Star Wars fansite forum called BlueHarvest (I moderated there the last couple of years before the admin shut it down in 2008 or 2009). A couple friends and I then communicated via a forum we made for ourselves. Then Facebook, then Reddit...now here.
EDIT
I also had accounts with MySpace and Friendster too...Twitter for a few years around Arab Spring, but I didn't like it. Even back then The Bird was a toxic mess with rare moments of humanity. I think my avatar is still shaded green...if my account still exists.
