It certainly feels nostalgic to me being on here. I miss the days of webrings and message boards and just crawling ever forward into unknown new places. I was a kid then though, so I thought it was just me becoming wiser/more tech-savvy. Now I realize how freaky all the consolidation is. Even some video game modding communities now have more of a presence on reddit than anywhere else. It's convenient but so weird.
I agree with u/Pelicanen that it feels like the uncertain times of the early internet where things were hosted by individuals and their really small websites. I don't know to what extent it will catch on (although Discord is huge with milleninals/Gen Z, no?) but it's interesting to imagine a world where the internet is primarily large consumer/business-facing websites and then highly decentralized communities.
