It’s gonna go public eventually, this is like a closed beta kind of thing. The purpose seems to be more to get people curious about it and foster a certain culture which I must say that they’ve been pretty effective at. They strategically handed out invites to a lot of black twitter users for example, which is smart since black twitter has historically been an important cultural force on the internet
They’ve been invite only since before that, it’s unrelated
Depends on in what way you’re looking for a youtube alternative!
I think peertube might be fine if you’re looking for a way to host your own videos, but it’s propably not a good place to just browse for video content the way you might with youtube. I think the most solid alternative for that is Nebula. It costs like a dollar a month IIRC and has a couple big name video easayist kind of types. It doesn’t really have anything to do with the fediverse or anything, but a majority of it is owned by the creators and from what I understand it is more generous per view than youtube, plus it has a buissiness model that doesn’t rely on serving you adds and selling your data.
There have been talks about tumblr joining the fediverse which seems like a similar scenario!
I don’t think there’s any risk of someone stealing your kbin account with this, however I do think that admins can access more data than normal users, including from federated instances. They where only logged in on the web, and I think you can only access that kind of data by accessing the database more directly, which the exploit wouldn’t have allowed the hackers to do.
Imo part of the problem with mastodon, at least in my experience, is that it’s sold as a twitter replacement while still being devoloped and largely populated by people who don’t like twitter (because it’s too “toxic”). This means that you can’t really have the twitter experience on mastodon by design so people coming from twitter mostly wanting to get away from musk bounce of. Bluesky has been a more successfull twitter replacement and I think that’s largely because it basically is twitter with feeds.
I think that mastodon should either commit to being more like twitter (which it is propably too late for at this point since I don’t imagine that their current userbase would be into that) or people should stop trying to make it the new twitter and instead let it be it’s own kind of different thing.
