I'm looking to expand my Bluesky feed with accounts that share interesting, tech-related content, similar to what we discuss here on HN.
Edit: saw a lot of valid responses, thanks! My question is answered and I might sign up on bsky as well if I get bored on Mastodon or want to connect with someone there :)
It's an open protocol, but more like the www than email. You can port your identity to another host at any time. You can self host if you want. You have complete control over how your chosen feed algorithm aggregates posts from the firehose. If you want to make a competing service to Bluesky you can even do that, and it will still interoperate with all the Bluesky users.
Whereas with Mastodon, when you pick an instance you're essentially picking which benevolent dictator you want mediating your experience. Mastodon is decentralized in the sense that it breaks the platform up into smaller fiefdoms; Bluesky is decentralized in the sense that you retain control over your own experience.
Some recommended reading on Bluesky/atproto:

Wait what? All of the benefits you mention for Bluesky apply equally to Mastodon (in both cases you can host your own thing if you like), and the latter (downside) applies to Bluesky when you sign up with the official server right? What's the difference you're pointing out?
They don't equally apply.

You can host things, sure, but atproto (this is really more about the protocol than the application layer) has true account portability, whereas Mastodon does not. Moving your account on Mastodon account has multiple options, all of which are closer to redirects: https://docs.joinmastodon.org/user/moving/
This all also requires cooperation from your host; if you're kicked out, then you can't do any of this. A profile redirect only stays up as long as that host is up.
Whereas with atproto, you can move between PDSes, and nothing will change with regards to your social graph. If your old PDS kicks you out or dies, you can recreate all of your data onto your new PDS by replaying it off of the relay.
That is, with Mastodon, your identity and your data storage are linked, so changing your identity requires changing your data storage, and changing your data storage requires changing your identity. But with atproto, these two things are separated, so changing one does not require changing the other.
Even if you sign up via bsky.app, there isn't even one official server: they partitioned their userbase among a bunch of different PDSes.
My understanding is that Mastodon wants to build the feature where you truly move your data into a new identity. They have the export working, but not import. So ultimately this will work as well.
