This plugin monitors a <a href="http://www.intertwingly.net/code/venus/" title="Planet Venus" rel="nofollow ugc">Planet Venus</a> cache 
directory and syndicates new entries as posts. 
It automagically creates users and categories as necessary.
The plugin was originally released on <a href="http://www.wasab.dk/morten/blog/archives/2006/10/22/wp-venus" title="WP: Venus" rel="nofollow ugc">Binary Relations</a> by <a href="http://www.wasab.dk/morten/" rel="nofollow ugc">Morten Frederiksen</a>.
<h3>Maintenance</h3>
When running correctly, the WordPress Venus plugin automatically adds users, categories and posts as needed, based on the information in the Atom entry files from the Venus cache directory. Each Atom entry file is only parsed when created or updated, so you may update existing posts, categories and users in WordPress as needed, in case something looks odd — your changes will not be overwritten unless the entry file is updated. If you delete a post, the plugin will try to remove the corresponding Atom entry file in the cache directory as well. For that to work, the web server process needs write permission to the cache directory.
If you find that the same users suddenly appears more than once in the WordPress user system (this may happen if the same user posts from different sources), you can use the Venus options screen to merge the two into one. The merge will be preserved for future arriving posts. This is accomplished by storing unique IDs for each user, as can be seen and maintained on the user edit screen.
Since the plugin scans the Venus cache directory to look for updates, you will likely find, that it slows down after a while. You may want to clean out the cache directory every now and then, possibly through the use of a cron job, and Venus’s -x switch.

WP-Venus

A plugin for running a syndication planet using Planet Venus through its cache directory, with complete support for multi author feeds and categories.

David Shanske

It supports adding links to your WordPress posts, pages, and comments, indicating where a syndicated copy is, in the form of a text or icon link. You can do this 
manually or with supported plugins. Also contains a generic UI for syndicating to other sites through your site or a Micropub Client.
<h3>Privacy and Data Storage Information</h3>
This plugin stores syndication links, which can be attached to any post, page, or comment. They can be added to custom post types by filter.
For webmention initiated comments, this information will be added by parsing the source of the webmention. 
It is assumed if you send a webmention, you consent to share this information if it is publicly shared on your page. Our recommendation 
is that site owners should take down information on request.
For comments initiated on the site, there is built-in way to add these links. For posts, they are typically added by retrieving information stored by other plugins for display. It is assumed 
that by installing this plugin, as its intent is to display these links, that you wish to display them.
<h3>Settings</h3>
Settings for the Syndication Links plugin can be found in the main WordPress “Settings” tab in the 
admin dashboard, or if the <a href="https://wordpress.org/plugins/indieweb" rel="ugc">Indieweb plugin</a> is installed, under the Indieweb tab. The options provided allow for various ways of presenting the syndication links in posts. Syndication Links by default will add links to the content. You can remove this in your plugin if you wish to call the display function directly.
The settings include the following options as follows with either a set of buttons, a check box (with a check indicating that the feature is “on”) or an optional text field:
<ul>
<li>Display Text – Offers options to display text only, icons only, icons and text, and no display(hidden icons).</li>
<li>Size – Choice of small, medium, or large size icons.</li>
<li>Black Icons – Checking the box defaults to a “black” social media icon set.</li>
<li>Show on Front Page, Archive Page, and Search Results – If checked the icons will show on pages other than a single view. If not checked, the icons will be hidden by the links will remain.</li>
<li>Show on Feed – If checked the icons will show in your RSS feed as well</li>
<li>Text Before Links – This is the text that appears before the Display Text/Icons (as indicated above). The default text is “Syndicated to:” but can be modified if desired.</li>
</ul>
Note: The particular CSS of your theme may change the display and output of the text and some of the icons.
<h3>Supported POSSE plugins and implementations</h3>
The plugin supports automatically pulling data from plugins that syndicate your content so you don’t need to do it manually. For anything not built in, integation is easy with a simple filter for potential use with any other plugin.
<ul>
<li><a href="https://wordpress.org/plugins/social-networks-auto-poster-facebook-twitter-g/" rel="ugc">Social Networks Autoposter</a> – Syndication Links supports Twitter, Facebook, and Tumblr since version 1.0.0</li>

</ul>
Using the optional Syndication feature(disabled by default) you can syndicate your posts to:
<ul>
<li><a href="https://brid.gy" rel="nofollow ugc">Bridgy</a> – Bridgy is a service that allows you to post to various sites. Signup is required. It currently supports Github, Mastodon and Flickr. The plugin supports Bridgy Publish via Micropub by default.</li>
<li><a href="https://fed.brid.gy" rel="nofollow ugc">Bridgy Fed</a> – Bridgy Fed is a service that allows you to interact with federated social networks using webmentions.</li>
<li><a href="https://micro.blog" rel="nofollow ugc">Micro.blog</a> – Micro.blog is a social network and publishing platform for independent microblogs, created by Manton Reece. It uses a custom feed you can add to Micro.blog to support this.</li>
<li><a href="https://pinboard.in" rel="nofollow ugc">Pinboard</a> – Pinboard is a bookmarking site. The support for this is currently only enabled if you have Post Kinds enabled, due to the difficulty in getting a URL. It will bookmark the URL of any object you are citing.</li>
<li>Custom Webmention Syndication – Add any site that supports publishing by sending a webmention by configuring it in the settings page</li>
</ul>
Will be looking to integrate with other plugins to add more options and invite developers to add support if they wish as the interface is simple. 
The goal of the interface is not only can you syndicate via Micropub, but in the editor using a simple checkbox.

Syndication Links

This plugin is not perfect but is very useful and a great way of getting involved in the indieweb.

Get on board

Easy to use, works with Gutenberg!


It's convenient to have remote links all in the footer, where they're noticeable but not obtrusive, and marked up so that IndieWeb software will recognize them. Works great with both WordPress and ClassicPress.



I've had less success trying to auto-post through Bridgy, but that's at least partly on Bridgy's side.


Simple tool to keep track of cross-posts

Link to copies of your cross-posted content in other social networks or websites.
