Had the same thought. Growing up in a small town (couple of hundred inhabitants), internet access early 2000's was a gift for teenage me. I joined web forums and discovered new interests (=web development which lead to my career), chatted with friends on msn, later played runescape and wow and met friends I later traveled countries to meet.
Of course, these things were different than the beasts today. Everything was more personal, smaller. No algorithms.
So not sure what I feel. Social media as we know it today is obviously bad (not just for teenagers). But maybe I'm just nostalgic for how it was.
But what about hn?
Are you describing the difference between a social network and social media?
