Send a Webmention in 10 (or fewer) lines of Python code | James' Coffee Blog
Webmentions enable distributed social interactions over the web. Using webmentions, you can send replies, likes, and other interactions that were published on your site to respond to another web page. For example, I send Webmentions for all of the bookmarks I create on my website. If a site can receive Webmentions, they will be notified that I bookmarked their post for later.
