I think the parent is referring to content creators and people who want to reach a large audience. These people will naturally gravitate to the largest hubs to minimize the amount of work required for maximum reach.

Personally I think that whole aspect of social media is toxic so I don't care, but others are not going to agree. I'm happy with an enclave where I hear the people I want to hear and am not hit with a bunch of spam and propaganda.

Mastodon is a failed product because Mr Beast doesn't use it? I don't think that makes sense.

The siloes may actually (re)boot a working 'society'. Word of mouth, social introduction, [restricted/specialized] meeting and discussion spaces, created the original (RL) societies. Societies originally emerged from a disconnected human background. The same can and likely* will happen again.

* Generative AI's gift to human intellectual and cultural rebirth will actually be due to its motivating the birth of numerous curated spaces of discourse and interaction, with strict AI content policies. I predict there will be a cambrian explosion of these boutique spaces. And society 2.0 will emerge from this.

Mastodon is likely better off if "content creators" avoid it.

Hear, hear. I was there in the time of webrings and it was glorious! All sorts of quirky little works of art waiting to be discovered.

Then came the monolithic social networks, and we collectively changed from the weird and wondrous adventure mode into the TV-dinner that is the web nowadays. Neither is perfect, and I'm not sure at all how to have both. But I'm glad the pendulum is swinging a tiny bit back.
