I's heard news that BlueSky has been growing a lot as Xitter becomes worse and worse, but why do people seem to prefer BlueSky? This confuses me because BlueSky does not have any federalization technologies built into it, meaning it's just another centralized platform, and thus vulnerable to the same things that make modern social media so horrible.
And so, in the hopes of having a better understanding, I've come here to ask what problems Mastodon has that keep people from migrating to it and what is BlueSky doing so right that it attracts so many people.
This question is directed to those who have used all three platforms, although others are free to put out their own thoughts.
(To be clear, I've never used Xitter, BlueSky or Mastodon. I'm asking specifically so that I don't have to make an account on each to find out by myself.)
Edit:
Edit2: (changed the wording a bit on the last part of point 1 to make my point clearer.)
From reading the comments, here are what seems to be the main reasons:
Federation is hard
The concept of federation seems to be harder to grasp than tech people expected. As one user pointed out, tech literacy is much less prevalent than tech folk might expect.
On Mastodon, you must pick an instance, for some weird "federation" tech reason, whatever that means; and thanks to that "federation" there are some post you cannot see (due to defederalization). To someone who barely understands what a server is, the complex network of federalization is to much to bare.
BlueSky, on the other hand, is simple: just go to this website, creating an account and Ta Da! Done! No need to understand anything else.
The federalized nature of Mastodon seems to be its biggest flaw.
The unfamiliar and more complex nature of Mastodon's federalization technology seems to be its biggest obstacle towards achieving mass adoption.
No Algorithm
Mastodon has no algorithm to surface relevant posts, it is just a chronological timeline. Although some prefer this, others don't and would rather have an algorithm serving them good quality post instead of spending 10h+ curating a subscription feed.
UI and UX
People say that Mastodon (and Lemmy) have HORRIBLE UX, which will surely drive many away from Mastodon. Also, some pointed out that BlueSky's overall design more closely follows that of Twitter, so BlueSky quite literally looks more like pre-Musk Xitter.
Most people don't know much, and don't care that they don't know much. Half of US adults can't read at a 6th grade level. They don't care about and probably do not understand complex topics.
That's it. They just want cat gifs, and that's the end of the thought.
I knew someone who was smart and successful and politically aware. She didn't care about any of this. She was tired from work and just wanted the familiar ease or twitter. Trying to figure out which server to sign up for and finding content was too much work.
A lot of people have executive dysfunction. Making a choice is hard.
I honestly don't get the whole "picking an instance is hard" thing, especially with masto. "Just use the default instance, mastodon.social, unless you have a reason not to," bang problem solved. Then it'd become a larger point of failure but if it went down "well now that you sorta understand it make an acct on the server most of your follows were on," bang 'nother problem solved.
Hell I have been diagnosed with executive function disorders and I can figure it out, it's not as hard as people pretend, we've all done it with email since like '95. "It's hard" is just twitter/bluesky propaganda!
Like I said "sure that makes it a bigger point of failure, but if it ever goes down just make one on whatever server most of your follows are on."
As for the moderation issues, maybe, idk, but then again if you're unhappy with the moderation by the time you get to that point "federation" is no longer a big scary word and you've likely found an instance you'd like to move to by virtue of just seeing it on your feed in .social, and on top of that masto lets you migrate accounts even, so it makes that a lot less painful to do.
Some instance have different rule as well as block other instances which will throw anyone off especially if it a big well-known instance like Mastodon.social which alienate large userbase of Fedi.
Tbf, some people want that. I prefer my instance which federates with anyone willing making you choose what to block yourself (aside from the reactionary instances that don't like that we don't block their enemy instances by default so they block ours, of course), but not just anyone can join my instance, so I can't recommend that unless they qualify. If you have a better general instance I can recommend instead of .social I'll definitely check it out!
My point is that it not everyone (newcomers especially) would know about various Fedi instances having a blocklist and some even blocking much popular instances. You are assuming that they would at least read usually large list of blocklist or admins even share the blocklist in the first place and check to see if it doesn't block the instance which has the user they want to follow and interact with.
I get the impression that some people have such decision fatigue, asking them to do something seemingly trivial is akin to asking someone without limbs to pick up a spoon.
