its about blueskys volume reaching a 'critical mass' which will continue to then draw users.

huge groups (recently, brazil) moved there en-masse because it already had a ton of users.

its the same reason twiiter even still has users.. they dont want to leave that volume of subscribers.

I agree with the other commenter's points, but one thing I think people forget to mention is that BlueSky feels like Twitter in a way Mastodon just doesn't. When I am trying to pitch Mastodon to people, I usually compare it to Tumblr because the vibes are similar.

Mastodon is also flat out hostile to influencers, and by that I mean the platform is designed to be terrible to influencers. The lack of an alogarithm means you can't game the system, no quote tweets means you get less opportunities to spread, no reply limiting means your notifications are going to be going nuts from the replies. The culture on Mastodon is difficult to game too, since people there expect thoughtful responses to their replies.

Just because BlueSky isn’t federated doesn’t mean it’s (totally) centralized. It uses the AT protocol which means user data lives in a separate place than the app itself. While the BlueSky app is centralized all the user data (your posts, likes, etc) live in a separate place and can be self-hosted. This means that if BlueSky went bust or something, users could easily just move to a new platform that someone would inevitably create and all of their data, likes, follows would all be there.

Because federation is confusing to the general populace

People don't care about federation. Or vendor lock-in.

I haven't tried bluesky, but mastodon seems a little broken by design. I'd you go to a post you are always told that the host server may have more replies. Things like that make it seem immature and perhaps just a bad solution compared to a monolithic approach.

If you don't like the instance (why wouldn't I?) you can just move to a different one. Yes, and restart my network. It's not really a good solution. I would like to exist on mastodon and just use some server. If I don't like it, continue somewhere else.

Bluesky is more similar to Twitter and has what most people were used to, like an algorithm, quote tweets, etc I found it extremely boring, but tbh it's a more polished experience. One of my biggest annoyances with Mastodon is how threads and replies look weird. Sometimes I see the reply to a post before I see the post, especially in the "lists" view. Also not having an algorithm is both good and bad. It's great because it's organic, but it also means many posts get buried and it's dependent on the time. As someone not living in the US and Europe, it's tricky because sometimes you'll post something when most people are asleep and no one will see it. I ultimately love Mastodon more because of the openness and the federation. But most people will find Bluesky more approachable

A lot of people are offput by having to choose a server before creating an account. If that could be automated somehow I think Mastodon would be more popular.

The federalized nature of Mastodon seems to be its biggest flaw.

Just to be devil's advocate, perhaps the federated nature of Mastodon could be its greatest strength as well. Isn't part of the point of all of this to avoid too much centralized control of social media?

Sure, Mastodon may never have as much mainstream appeal as BlueSky, but I use both. One of the reasons why I like Mastodon is precisely because I want to interact with more of a niche community on a federated platform. To interact with the masses on a platform that is more centralized, I use BlueSky.

Bluesky is more like Twitter, and Twitter users prefer Twitter to Mastodon

I’m gonna echo what others have said here. The mastodon signup process is too complex, and searching for instructions just leads to “what is the fediverse and/or activitypub” explainers.

I created a mastodon account a few years ago and it was my first introduction to the fediverse. It was frustrating and I only persevered because I REALLY wanted to replace twitter.

Once I got it set up, I realized that no one who I followed on twitter was there. My feed is currently like 2 people, plus a bunch of dead accounts from people who dipped their toe in but didn’t stay.

Joining Bluesky was simple, and there were already a bunch of accounts I wanted to follow. The recent influx has increased that, and it feels a lot like old school twitter without the nazis.

People originally joined twitter (and stuck with it for so long) because that’s where everyone else is. Mastadon is too clunky join and use, so people aren’t.
