My first online experience was with CompuServe. Quite frankly, I have yet to come across any social media platform that competed with Compuserve.

That is probably because people had to access it with a dial up modem the forums self policed to minimize low quality content.

PS: I also used Usenet. Usenet didn't do the threading as well. So the discussions I followed kept getting destroyed by flame wars and spam.

Lol, those were the days,...
I remember CompuServe, my buddy had it.
He bought an apple before he knew IBM clones were gonna betamax him.
