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

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 communities 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 - for example: on Reddit we have had r/trees and r/marijuana_enthusiasts and I've seen that implemented into Lemmy instances already. I wouldn't get rid of that, I think there are some traditions that are neat and don't harm anybody.

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.

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.

So, it is recommended to either join one that fits your niche or maybe to self-host?

According to fedidb.org, the entirety of the Lemmy network (that uses the Lemmy software) has 140,442, while the entirety of the KBin network (that uses the KBin software) has 32,830.

I can't see new posts from kbin on l.world anymore so idk what's happenning

Old posts and comments will be seen, new ones won't be seen. One-sided defederation is like two linked servers delinking from one another - you keep the old info but you basically desync and one side can't see the other if they add new stuff.
That's why I have accounts on both kbin and l.world - so that I am able to access more information as it gets updated. It seems the influx of new users is leading to a fracturing and a defederation of the biggest instances, so having one account for all of the threadiverse is not viable.

I was never able to sign up or log into Beehaw. It's very limited in terms of who it allows to sign up, and the waitlist is probably incredibly long.
This cutoff means that I'll have to live without being able to participate in a lot of discussions, which defeats the purpose of joining the fediverse entirely.
It's just as useful to me as using Reddit right now, even less so with how much less popular Lemmy instances are currently.
