Dimensions of Communication
Quote: "All the communication technologies we use -- telephones, newspapers, radio, IM, e-mail, mailing lists, TV, books -- are mired in historical cruft that keeps us from seeing clearly what to build next."
Comment: Short read...presents communication in the following dimensions: timing, audience, mode, length, persistence, production level, identity, and permission. I would add "need for communication"...while not directly a dimension of communication, it certainly drives the characteristics listed.
