I just received my invite code today and took a quick look around the app. Like Mastodon I do not prefer microblogging platforms. And that's all I know about Bluesky.
It's twitter except for the old guy instead of the new guy. If you left twitter for bluesky then you are likely just going to run into the same issue down the road where the old guy sells it for tons of money to whoever will pay. Those willing to pay are likely not great at managing a social media platform.
I wanted to like Mastodon but couldn't. The only reason I used microblogging services like Twitter was to shitpost about Vampire: The Masquerade. Said game includes lots of death, blood, and other topics that make some folks uncomfortable. On Twitter, the atmosphere was very "don't like, don't read", but Mastodon has an intense culture about using content warnings on anything that might make someone marginally uncomfortable. I'm cool with that, but I can't do it on my shitposting or it sort of ruins the joke. Bluesky doesn't have that atmosphere.
I know folks usually skew that way but it’s server to server. Frankly, I don’t use any warnings because I can’t be bothered and my instance is fine with it.
That misunderstanding proves how we need to review the user experience of federated projects, or at least do a much better job of explaining it to everyone.
When everyone migrated there were a lot of "helpful" newbies enforcing rules that simply don't exist. There are too many people like that still but not so many you can't mute them all.
They have a sandbox environment federating with 3rd party servers where other devs can participate in testing, and in the main public beta environment they just switched away from one main server to like a dozen (still no 3rd party there) and moved user accounts around, so they can test the federation code for stuff like performance and effects of account migrations, etc, in a live environment.
They've said they won't open up federation with 3rd party servers on the main environment until they have moderation tools which can handle it, so they're working on that also now.
