What’s This About?
WordPress.com delivers blog posts and comments in real-time. Anyone can subscribe to their favorite WordPress.com blogs and receive posts and comments the instant they are published. Soon the conversations on blogs will be as fast as chat rooms.
How Does it Work?
Jabber (XMPP) is an open instant messaging protocol used by millions of people daily. At WordPress.com we use Jabber to instantly deliver new blog posts and comments to subscribers.
