Plugin that provides a Gutenberg block and an <code>[include-mastodon-feed]</code> shortcode to easily integrate mastodon feeds into wordpress pages. Supports personal and tag feeds.
Account and post images are lazy loaded if preserveImageAspectRatio is set to true (default: false).
The plugin is written in PHP and generates native JavaScript to fetch and render the mastodon feed. No special libraries needed.

Include Mastodon Feed

This is a very early state of a salmon-plugin for WordPress. There are still some bugs and problems… Please 
let me know if you found some.
<blockquote>
As updates and content flow in real time around the Web, conversations around the content are becoming increasingly fragmented into individual silos. Salmon aims to define a standard protocol for comments and annotations to swim upstream to original update sources — and spawn more commentary in a virtuous cycle. It’s open, decentralized, abuse resistant, and user centric.

You can find more informations about Salmon here: http://www.salmon-protocol.org/
The plugin currently only supports receiving Salmons, but I am working on a bidirectional version.
This plugin requires the following plugins:
<ul>
<li>the <code>host-meta</code>-plugin: <a href="https://wordpress.org/plugins/host-meta/" rel="ugc">https://wordpress.org/plugins/host-meta/</a></li>
<li>the <code>webfinger</code>-plugin: <a href="https://wordpress.org/plugins/webfinger/" rel="ugc">https://wordpress.org/plugins/webfinger/</a></li>
</ul>
and I recommend to use it in combination with OStatus: <a href="https://wordpress.org/plugins/ostatus-for-wordpress/" rel="ugc">https://wordpress.org/plugins/ostatus-for-wordpress/</a>
