Fediverse

It creates that "one big chatroom" vibe from old twitter, while Mastodon feels like a bunch of people microblogging next to each other

I think emulating twitter was a huge mistake for mastadon, the twitter reply structure that makes it difficult to have a long conversation with multiple people to be the main part of the post but ideal for "dunks" and outrage farming. I think the Tumblr reblog structure would have been an infinitly better choice for the more actual socialising thing fediverse is going for and a small user base that isnt producing much content and can re-circulate older posts. also it's less image-centric allowing more posts to be stored on a server, additionally (intuitively, I haven't thought about implementation that hard) it seems like a much more natural fit for federation.

If you go on Bluesky they will tell you. Lots of people saying that they feel isolated because there is no algorithm feeding engagement, and federation doesn't lend itself to finding your friends from Twitter easily without one of those migration tools people were using. Then another chunk describe Mastodon users as a "HOA" because someone told them to put a CW on something.

Portable accounts and being able to add third party layers to your feed for moderation and sorting algorithms. At least that's their design goal, idk if it's actually implemented because I never got an invite after like half a year.

Main positive thing I’ve heard is that it has a different vibe and culture that some might find more open and fun and sometimes even less problematic. That’s just hearsay, I’m not on there, but I’ve heard it from people I like and trust (on masto).

More non political stuff most likely.

Lots of semi naked dudes and I still don't know why!

As much as people may not like to hear it Ease of use from being one centralized platform is a big factor

Just login and be done with it

Being invite only makes it seem like some kind of cool club.
