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

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

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

"Third reply downvotes" and other types of bullying done for absolutely no reason. Also, people misleading others to disgusting subreddits just to troll them, for example (and I am paraphrasing the names of the communities): "misspell the community's name to c/vercute instead of c/verycute and you accidentally get a sub full of gore" or "check out c/audioing, it's definitely not people doing a very disgusting thing to one of their body parts". I do, however, like the fact they're bringing the whole subreddit swap meme (example: r/trees and r/marijuana_enthusiasts) into Lemmy/kbin, so I wouldn't get rid of that.

A couple things I would like to see on kbin:

Setting to switch the default homepage from "hot" to anything else, or add an option to only see posts from magazines I follow

Setting to move the "make a comment" box to a place that's above the comments

Otherwise, this is pretty much perfect so far.

It's your decision, and I hate Reddit and Spez ever since they decided to do the whole API thing, but personally, if I were to close my account, I wouldn't scramble all of my comments and posts. It makes it harder for people who still search for answers to questions on reddit to find what they're looking for. You aren't preserving valuable information with this, you're destroying it.

It feels different to use fediverse-based forum sites, but they're growing rapidly, and you find new communities/magazines pretty much every day, and even though there's some fracturing going on (need I remind you of Beehaw defederating from .world).
I like this a lot more than the social media-esque approach of modern Reddit. It has very much become like Twitter, with it's endless feed of dopamine-inducing algorithms and whatnot. The blackout is a bit annoying, but I agree with the fact people should protest decisions if they ruin things for people.
I'm liking the experience so far.

Native apps? Because I sure hope so.

They did make a poll and then later announced they'll be banning underage anime art and IRL imagery . But not art of cute/short characters because it's impossible to discern if they're over 18 or not. It's the whole Pokemon debate all over again.
