Maybe Bluesky is not quite the Twitter rival it set out to be, but it's got a better shot than Mastodon, according to the user count graphs here:
https://mastodon-analytics.com/
Bluesky has a higher total user count. I think the number of active users might be higher too, but I am not sure what's mastodon's definition of an active user for the second link above. Anecdotally, Bluesky feels more lively for me because that seem to be the default destination for Twitter refugees.
If Meta had put Threads on the AT protocol instead of ActivityPub, things could have been so different... maybe there's still time. The engineering philosophy for AT / Bluesky is incredible, being able to develop your own timeline algorithms, distributed moderation agencies, etc. But whenever I give Bluesky a try unfortunately I just can't find people talking about my interests. This seems like a scale problem, which Threads solves.
We have ample evidence that platforms whose goal is to shove everyone you've ever met into the same room isn't a good thing. Modest growth and a healthy community that doesn't have to include everyone to succeed seems like a good thing.
Toni Schneider was just on Decoder last week too talking about this and more

there's nothing you can do technically to fix bluesky.
people just hate social networks at this point in this timeline.
The only promising social network to me was that browser extension that let you comment on every single page, but it was shut down when people freaked out that it (obviously) sent the URL of every page you visited to their servers. I've wanted something like that for so long. There just isn't enough thread-based discussion happening online. It's all buried in what are essentially darkweb chatrooms (unindexed Discord chats)
Reddit is dominated by the left, but there are other voice audible.
Twitter has plenty of leftists. They are very, very, very easy to find, as is every other shape and size of political, ideological, or spiritual thought; far easier than, say, a non-leftist viewpoint on the worldnews or politics subreddits, which because of their default status are much more inescapable than any one Twitter account.
There are very, very few non-left people on Bluesky. "JD Vance Becomes Most Blocked Person on BlueSky Days After Joining App" <https://www.newsweek.com/jd-vance-bluesky-blocked-social-med...>
Even Bluesky's top users say so.
"Bluesky is backfiring. Mark Cuban says the 'lack of diversity of thought' is actually pushing users back to X" <https://fortune.com/2025/06/12/bluesky-backfiring-mark-cuban...>
"Bluesky is not the good place" <https://www.ms.now/opinion/bluesky-elon-musk-twitter-replace...>
But it could be worse. Bluesky has block list dissemination (à la how, if you make one comment in a "wrong" subreddit, a whole bunch of others will automatically ban you despite never having even heard of them), but I don't think even it ever gets so bad as individual Mastodon instances' ability to self-destruct in spectacularly amusing fashion. mastodon.lol example over Hogwarts Legacy. <https://news.ycombinator.com/item?id=34748195> As rvz said in the link,
>This is just one of many Mastodon instances which are undergoing an extinction event which involves: turning against themselves and destroying each other. This time, it is over a children's video game.
That said, I suppose that such self-immolation might be a good thing; sort of an immune system-like response. There are many, many mentally ill that steep far too long in Bluesky (and 80% of Reddit)'s ever-boiling toxic soup.
I hope against hope that people started to realize that the problem isn't the platform, it's the entire approach.
Who am I kidding, people just realized that Bluesky wasn't going to be the next big thing and so it collapsed into being a mediocre bubble like Twitter, but without the scale.
Interesting quote:
"For Bluesky’s new CEO, Toni Schneider, these numbers may not be as concerning. The company is not entirely focused on making Bluesky (the app) succeed, but on making it possible for the underlying protocol (AT Proto) to power a growing number of social apps, services, and communities."

Bluesky's feed algorithm (the "Discover" tab) is the worst I've ever seen. Hands down. I can't imagine anyone enjoying it unless they're 1) super into the US politics/domestic issues AND 2) politically aligned with the main user base of Bluesky.
The funniest part is that there is a better algorithm. It's right here: https://bsky.app/profile/spacecowboy17.bsky.social/feed/for-...
But somehow the devs of Bluesky never thought of making it the default tab. They should be making a better Twitter but what they're actually building is just Truth Social for the left.
