Pingcrawl aims to replicate WordPress.com’s “Possibly related posts” capability. It queries Google Blog Search for related blog posts (based on tags, or the post title if there are no tags), tries to verify that they are pingback/trackback compatible sites and, if so, adds links to such posts to the end of each blog post where it is invoked.
Scope-limiting configuration options are included to enable Pingcrawl to fit any WordPress installation’s memory/execution time budget.

Pingcrawl

Pingcrawl adds a "Possibly related posts" capability by querying Google Blog Search for post tags and pinging the results.

When you link to a website you can send it a Webmention to notify it and then that website may display your post as a comment, like, or other response, and presto, you’re having a conversation from one site to another!
A <a href="https://www.w3.org/TR/webmention/" rel="nofollow ugc">Webmention</a> 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.

Webmention

Easiest way to integrate Webmentions!

This is fantastic. I joined indieweb a few days ago. Last night I wanted to know "So what actually does the technical implementation of a WebMention look like?". I am now working on improving my understanding and perhaps I'll create some documentation that I find easier than the w3c spec or a WP plugin.

Great work, very patient team.

Wonderful

A good plugin that does something very useful. Love the indieweb and Matthias Pfeferle does such great work
