Nostr web apps should work on URL previews! It turns a lot of people off especially normies when they see a generic preview for a link, previews are stqndard, thats how we judge links before opening them!
Also it incentivizes you to move away from free hoating like github.
Does CORS mess up Opengraph tags with Nostr basic architecture? (I really don't know, myself, but it seems like something that might be a problem, and you would know more.)
Nah, most apps do preview well, they just dont preview dynamically, like it will preview the app even though im sharing a link to a post, most modern apps woild preview whatever is the content of the link
