The humor is way more redditty on lemmy. Which I realize sounds nonsensical, but a huge portion of lemmy users are former reddit users who both think reddit humor is funny and have like 10 years of reddit humor memes to draw on. The “early” (2012ish) reddit I’m remembering had less of that and a lot more of what current users would consider cringe, like f7u12 comics. And a lot more general weird nerd awkwardness… like the frozen soap post.
