I’m a decade older, but I feel like a lot of people who left for Lemmy were active on Reddit 10-12 years ago, and have preference for the flavor of discourse of that time. As it grew, reddit became far too sarcastically meta in a lot of ways. What was once a spicy “in joke” became boilerplate. I’m not surprised at the exhumation of the old memes. It may just be a phase of some sort, a necessary reset, who knows?
