Ok, so I found a novelty account on X/Twitter ("Quest 64 Official") that has been spreading Quest 64 memes and think it's hilarious, so I've been reposting them to Lemmy.
I like to think I'm immune to anything people could post from my time on the early days of the internet, but yeah, it's like a sea of totally unfiltered opinions/content over there. There are still a lot of good fandoms, memes, news, etc., but you have to also scroll through conspiracies, political astroturfing, and every hateful thought that someone decided to write today.
Fortunately it's not the only place I casually scour for content for the fediverse.
