After attracting 2 million users in its first year of operation, Bluesky has grown another 400 percent with some recent help from Brazil and Elon Musk. Are these monthly or daily users, or just account holders? Nobody knows! But it still has a way to go to match X’s estimated 250 million daily users and Threads’ 175 million monthly users.

I mean thanks to bridgy you can communicate across blusky and mastodon. For example people can follow my mastodon account on bluesky.

And bluesky has gained > 8 million users in the past couple months. Mastodon has 900 odd thousand MAU.

So clearly the majority have gone to one.

I don’t know where you got that number from, but at least these statistics say Mastodon got 9 million users (but not all are active off course, same should be true for BlueSky): https://mastodon-analytics.com/ And this account claims 15 million: https://mastodon.social/@mastodonusercount and a Wikipedia article says “On 19 March 2023, Mastodon passed the ten million mark for registered user accounts”: https://en.wikipedia.org/wiki/Mastodon_(social_network)#2022_Twitter-related_spikes_in_adoption

Now, I do not claim these numbers to be correct. But compared to your estimation its vastly different.

Edit: Just for context of my reply, as you edited yours. You said you don’t believe Mastodon would even have 100 thousand users.

Even if your numbers are true. Mastodon has existed for 7 years. Bluesky for less than one.

So logically the precentage of users to active users should be much higher on Bluesky.

Also number of accounts is possibly a bad metric to judge mastodon because of the federation.

For example, I have 8 mastodon accounts (tried a couple different instances and programmed a couple rss bots to give me a news feed).

Even if your numbers are true. Mastodon has existed for 7 years. Bluesky for less than one.

That doesn’t matter, because most users just came in the last year. Just shortly after Mastodon begun to explode in 2023 from 2 million to over 10 (and now seemingly over 15 million) registrations, Bluesky came in. So the 7 years comparison doesn’t matter here.

So logically the precentage of users to active users should be much higher on Bluesky.

Probably, but without statistics its just our gut feeling. And as you saw a few minutes ago, your gut feeling can be drastically wrong. My point was not here to race count Mastodon vs Bluesky, but to point your estimation of Mastodon accounts being vastly underestimated.

According to Wikipedia Bluesky has 10 million users and 5 million monthly active: https://en.wikipedia.org/wiki/Bluesky That would be about what Mastodon has, if we believe those numbers. My point is, you totally over estimate Bluesky and underestimate Mastodon. The exact numbers does not matter here, what matters is my point that the user base is split into these two worlds.

So bluesky has 5 million monthly active users while mastodon has 1 million?

Thats a fivefold difference.

I was just correcting your initial 100k estimation of Mastodon accounts. That’s all. No need to get cocky.

Sorry I didn’t mean to sound cocky. It sounds like a byproduct of slow federation. As I edited my comment almost immediately (before you replied) after posting it, to correct said number and provide a source, but it doesn’t look like it got to your end.

Also MAU stands for monthly active users and not total users. But I realise that acronym may not be widespread.

I mean thanks to bridgy you can communicate across blusky and mastodon.

It requires to use a separate app like this which is not very convenient.

Comparing users to MAU seems disingenuous. The fediverse has ~12 million users, according to fedidb and around 1.1 million active ones.

Most of them on Mastodon.

True. So both have around 10 million total users. Bluesky has no monthly active user statistic. But around 1 million daily posters according to this https://bsky.jazco.dev/stats

While Mastodon has ~1 million monthly active users.

So sounds like bluesky’s got a lot more activity with that many daily posters, as of now, anyways.
