A Webmention is a notification that one URL links to another. Sending a Webmention is not limited to blog posts, and can be used for additional kinds of content and responses as well. For example, a response can be an RSVP to an event, an indication that someone “likes” another post, a “bookmark” of another post, and many others. Webmention enables these interactions to happen across different websites, enabling a distributed social web. The Webmention plugin supports the webmention protocol, giving you support for sending and receiving webmentions. It offers a simple built in presentation. To further enhance the presentation, you can install Semantic Linkbacks.
