I thought this was slightly funny.
Mark Zuckerberg is known these days for wearing t-shirts with Latin phrases on them, especially ones where he compares himself to Julius Caesar.
Bluesky made a shirt in the same style, but theirs says “a world without Caesars” in Latin.
Fair - you could host a copy or a link (or a sort of combination between the two, I guess), but it wouldn’t transfer the ownership of the original post. I’m still not sure this is such a pressing feature that I accept it as the actual raison d’etre of AT proto, especially considering how it very much exists there only in theory at best. But it is interesting technology, and something they could maybe have worked with ActivityPub to try to achieve.
I’m glad to hear that maybe Bluesky is more decentralized than I suspect, but Bluesky engineer whose blog post you linked still links to his bluesky account on bsky.social. If running a separate instance is achievable, I would love to see people actually do it.
My understanding is that running most of BlueSky is possible on small to moderate hardware. However, running all of BlueSky requires basically cloning 100% of all the content on BlueSky (which, as of Nov 2024, was ~5 TB).
So, like, yes, one can run part of BlueSky or a clone of BlueSky which has none of the main instance’s user’s content without much trouble, but actually running an entire BlueSky stack is eventually going to become cost prohibitive.
I found this write-up to be enlightening on the subject.
