I think kind of depends on how deeply you explored the instance list to find and instance that really vibes with you and makes you feel like excited to join. If you join one of the major ones like lemmy.ml or lemmy.world or shit just works or another one of the big instances, it'll just feel like the early days of Reddit — young and active and exciting because it's a new platform but not particularly unique feel or culture or anything because they're just general purpose instances that let anyone in and so kind of end up with a common denominator internet culture. If you really go far down the instance list, though, and find an instance with less than a hundred users that has a really particular theme, target audience, and user culture, like I did, then it feels radically different than any other social media platform. I think that being on the big instances kind of hides the fact that Lemmy is super decentralized, just like the early internet, and so can give rise to really niche, unique, diverse, and interesting communities.
