Discussion
The W3C webmention specification from 2017 (https://www.w3.org/TR/webmention/) is a more limiting implementation of #nostr NIP-08.
Here is how NIP-08 > Webmentions:
- webmentions need to push to the origin (through a notification). the website/blog needs to implement an endpoint to receive
- webmentions are not signed and not verifiable opening the door for spam
- if you miss the webmention, although it might be retried, it's gone
- NIP-08/nostr mentions support any content. Not just blog posts
