Can someone help me in understanding from layman’s perspective how this (Nostr) is or will be different from BlueSky?

Finally had a moment to read the recent Supreme Court case, 303 Creative LLC v. Elenis, 600 U.S. ___ (2023). This Court in this case agreed with a website owner in her argument that the State of Colorado may not force her to create websites for same-sex couple. On its face, I agree with the premise—the government cannot force artists/creators to make “art” in support of something they disagree with. But one has to wonder what would happen when ordinary products and services become “art” expressions? I agree with Sotomayor’s portrait studio example (pg 60). Just because photography can be expressive, doesn’t mean a school photographer can refuse to photograph black kids for a yearbook.

Ads are a pain … how does Nostr and clients like Damus allow users to limit/prevent ads?

So… new here… is this an alternative to Twitter?

Im new. What is this place?
