Libreddit does work, but not all instances of it do.

beehaw - tight-knit diverse, lgbtq and positivity reddit

Mastodon: open-source, in the fediverse, open for signups (depending on the instance)
Bluesky: proprietary, invite-only (for now), not in the fediverse but has its own network of domains

Out of the open platforms, I use:
Reddit: Lemmy, Beehaw, Kbin
Twitter: Mastodon, Calckey
Facebook: idk nothing really plus I don’t even use Facebook that much anymore

I may occasionally use proprietary ones like Twitter, Tumblr and Threads.

And I have nowhere to go but Kbin because Beehaw is unstable and I don’t want to open up a fourth account. Accumulating fediverse accounts should be the last thing you do
