Why should I use it?
MQTT is a great and easy way to exchange low frequency messages like sensor readings, or program states etc. between multiple machines and services. Its very robust with a small footprint.
It is based on the publish/subscribe paradigm and requires a central MQTT Broker.

Cool:

• You can host the broker in the public web and communicate with nodes in local networks.
• Which means you can communicate with your an Arduino anywhere on the planet which is connected to the internet:https://github.com/knolleary/pubsubclient
• The communication is asynchronous and won't block vvvv!

If you wan't to host your own broker have a look at:

• Simple but powerful broker:http://mosquitto.org/
• Full IoT stack including an MQTT broker for the Rasperry PI:http://thethingbox.io/

Funfact:
The Facebook Messenger is build on MQTT:https://www.facebook.com/notes/facebook-engineering/building-facebook-messenger/10150259350998920
