What I miss are the gaming communities. There is no talk about games I play on Lemmy, just general gaming communities and I never browsed r/gaming either. Biggest let-down: PoE even has a dedicated Lemmy instance but it’s empty and abandoned.
There is just not enough demand because only a minor fraction of reddit users got hit by the 3rd-party app slaughter. The vast majority doesn’t care and still stayed on reddit. It was the expected outcome.
Hot take of the day: What doesn’t help with this is how fractured communities are throughout the instances. What I mean by this is if I subscribe to “World News” on lemmy.world, I won’t see the posts from the same type community on other instances, like “World News” on beehaw, in my subscriber feed unless I subscribe to them too (or someone crossposts). This adds an unnecessary level of micro-management and probably also drives people away from Lemmy. The biggest strength of Lemmy is so-to-speak also its biggest weakness.
