Hubzilla Plugin enables PubSubHubbub subscriptions

A recent plugin was added to the Hubzilla Plugins Repo called Pubsubhubub.

PubSubHubbub is an open protocol for distributed publish/subscribe communication on the Internet. It generalizes the concept of webhooks and allows data producers and data consumers to work in a decoupled way.
PubSubHubbub provides a way to subscribe, unsubscribe and receive updates from a resource, whether it's an RSS or Atom feed or any web accessible document(JSON...).

This protocol is used as the subscription component of OStatus, which #GNUSocial supports. I enabled the plugin on my personal channel, which required no setup or configuration of any kind. After entering my handle into GNU Social's remote subscription form, my name and avatar appeared instantly.



I decided to take things a step further by sending over a test post. At the moment, it appears that old posts created before a connection is made don't get federated over. Still, it can correctly reflect any status I post on #Hubzilla.



Unfortunately, comments do not appear to federate back or forth at the moment.

Still, it's clear that this plugin is showing a massive amount of potential in connecting different parts of the federated web together.
