In all likelihood that experience will be temporary, in one of two ways. Either Lemmy becomes mainstream enough to enshittify beyond your tolerance, or Lemmy atrophies into obscurity and ceases being a platform with any benefit.
Which will happen, and on what timescale it will happen? Who knows. But I wager one of those outcomes is inevitable before too long. The "chill, somewhat unknown but appreciably active platform" position is long-term an unstable one.
Until then, we're all just in time to bask in the warm glow of this little experiment for at least a little while.
Decentralized/OSS platforms >>> Multiple competing centralized platforms >>> One single centralized platform
Bluesky and Threads are both bad but having more options than Twitter/X is still a step in the right direction, especially given the direction Musk is taking it in. As much as I like the fediverse (I won't be using either Threads or BlueSky anytime soon), it still has a lot of problems surrounding ease of use. Lemmy, Mastodon, Misskey, etc. would benefit a lot from improving the signup process so that the average user doesn't need to be overwhelmed with picking an instance and understanding how federation works.
Platforms like Twitter are incredibly useful for following public figures and journalists, your feed doesn’t have to be all brainrot. Having a similar platform that’s not in the hands of a billionaire freak is in the public interest.
