This is an auxiliary utility plugin. It periodically queries Podupti.me, a 
public service of Diaspora* community. It retrieves a fresh list of active 
Diaspora* servers (so called “pods”). The list is then stored and made 
available for other plugins (specifically 
<a href="https://wordpress.org/plugins/share-on-diaspora" rel="ugc">Share on Diaspora</a>).
<h4>API</h4>
To get the podlist from another plugin, use the following reference code:
<pre><code><?php $podlist = get_option('dpu-podlist'); ?>
</code></pre>
The result is an indexed array of Diaspora* server URLs.

<a href="http://nodeinfo.diaspora.software/" rel="nofollow ugc">NodeInfo</a> is an effort to create a standardized way of exposing metadata about a server running one of the distributed social networks. The two key goals are being able to get better insights into the user base of distributed social networking and the ability to build tools that allow users to choose the best fitting software and server for their needs.
This plugin provides a barebone JSON file with basic “node”-informations. The file can be extended by other WordPress plugins, like <a href="https://wordpress.org/plugins/ostatus-for-wordpress/" rel="ugc">OStatus</a>, <a href="https://github.com/pfefferle/wordpress-dandelion" rel="nofollow ugc">Diaspora</a> or <a href="https://wordpress.org/plugins/activitypub/" rel="ugc">ActivityPub</a>.
