Jon Udell – Pub/sub networking for enterprise awareness:
"In theory everyone talks to everyone and everything gets taken care of. In practice, as we know, not so much. Interpersonal messaging alone can’t create a resilient and discoverable web of connections. That’s why interpersonal messaging must be embedded in a pub/sub network where messages flow person-to-person, person-to-topic, topic-to-person, and topic-to-topic."
