This is the text and images from a presentation at the PressEd conference held online last week. As the title suggests, the focus is the use of Webmentions. The main idea of a webmention is that, when you want to comment on someone's post, you do the commenting on your site, and then send a 'webmention' notification to that person's site, which will then decide what to do with your comment. It's a distributed version of the automated comment systems provided by companies like Disqus or Facebook. Anyhow, the point of this talk is to mention the WordPress plugins supporting the Webmention standard.
