WhisperFollow turns your wordpress blog into a federated social web client. 
In it’s current form it aggregates RSS feeds in a page on your blog called “following” which it creates. 
The links it aggregates are the ones from your blogroll with rss feed data. 
Reblogs are automatically in the “whispers” category which can be excluded from pages if you like using plugins like <a href="https://wordpress.org/extend/plugins/simply-exclude/" rel="ugc">Simply-Exclude</a>.
This plugin will be updated to be ostatus compatible working with the <a href="https://wordpress.org/extend/plugins/ostatus-for-wordpress/" rel="ugc">ostatus-for-wordpress</a> plugin.

Use your wordpress blog to aggregate and reblog all friends and sites from across the web.
