Should you switch?
Use it if
People who want a Reddit-style link aggregator and forum they can self-host or join as a federated instance, away from corporate control.
You need a single central signup and Reddit's full community breadth: Lemmy is federated, so you choose a server and each instance sets its own moderation policy.
Federation comes with friction: instance choice, defederation disputes, and sparse niche communities are recurring complaints from people who tried it.
