So what is this PubSubHubbub stuff?
Here’s what the Googlecode page has to say about it.
A simple, open, server-to-server web-hook-based pubsub (publish/subscribe) protocol as an extension to Atom and RSS.
Parties (servers) speaking the PubSubHubbub protocol can get near-instant notifications (via webhook callbacks) when a topic (feed URL) they’re interested in is updated.
In short, it’s the reverse of Really Simple Syndication (RSS). RSS is the client asking the server if there are any updates. SubPubHubbub will tell the client that there are updates. There are a number of very popular protocols and applications that use this technology, such as XMPP, WebSockets, and previously, Google Wave.

Automattic, the team behind PuSHPress, recently updated the plugin to offer a stable tag up to WordPress 3.6 and just a one more improvement. The plugin has been around for about 3 years, but hasn’t seen much visibility.
Have you used PuSHPress? What did you use it for?
