title: What does MassTransit add to RabbitMQ?
body: <p>What is the benefit of building on top of <a href="http://masstransit-project.com/">MassTransit</a> compared to building directly on top of <a href="http://www.rabbitmq.com/">RabbitMQ</a>?</p>
  
  <p>I believe one benefit provided by MassTransit is 'type' exchange (publish subscribe by interface / type) so the content of the message is structured, compared to plain RabbitMQ exchanges where the content of the message is unstructured text / blob.</p>
  
  <p>What other benefits provided by MassTransit?</p>
