Because famous figures or organizations are the primary draw for the mainstream audience over random users. And many use it because they themselves hope to use the huge platform to promote or try to become an influencer.

You badly underestimate the proportion of people who have never heard of Mastadon.

Mastodon seems to be more confusing than Threads or Bluesky for most users

Giant corporations as a comfort zone?

Maybe being stalked 24/7 is their kink?

I'd bet most of the people on theads aren't looking for a "Twitter alternative" they just clicked on the button in the Instagram app. The rest are lost journos and clout chasers.

Very easy start and algorithmic feed, I think.

I’d guess there’s a few reasons.

Threads was able to be pushed through other large commercial platforms, and onboarding was trivial for anyone coming through the portal.

Mastodon lacks that kind of exposure and the onboarding process of choosing an instance makes it feel more confusing.

As a result, Threads starts off with a network effect that is quite a bit more advanced than Mastodon’s. It has more high profile users that maintain an active account. It also claims to want to join the fediverse, which makes users think that they can easily onboard with Mastodon in the near future.

I'm pretty sure "threadiverse" means Lemmy/Kbin which have threaded conversations, not Threads.

They're always trying to get more users and make it more popular too, when that's not the point of the fediverse.

Can you tell me more about this? I'm working on a tool that is attempting to help exactly with this type of migration from twitter/reddit to fediverse alternatives, perhaps I could try to set a Mastodon Mirror instance focused on specific twitter profiles.
