Are Bluesky and Nostr different? Searching tells me Jack's a major force behind both, but which is worth committing time and attention to? Are they the same thing and I'm dumb? Help a non-technical normie!

The best thing to do is go through the documentation
Read the overviews here
NOSTR:
https://github.com/nostr-protocol/nostr
AT PROTO:
https://atproto.com/guides/overview
And then I would recommend comparing the first 5 implication possibilities (NIPs) on nostr:
https://github.com/nostr-protocol/nips
To the identity / repo / lexicon / app sections of the docs on at proto:
it’s mostly plain English, you can still get a lot by just skimming past the json examples
