Actually, I think the premise of this thread is just wrong.
ALL communication is subjective -- it is between Viewpoint A and Viewpoint B. Even when a 1000 people ready an article there is only the same transaction -- AUthor A to Reader B =-- occurring.
When communication becomes mechanical, rote, automatic, scripted, it of course loses a lot of its life. That's what really obfuscates communication. For example try understanding the mind of the person who writes the fine pront in your credit card statement. Obscure? I'll say.
Subjectivity is the spice of life and the garden of independent thought, and the only channel to the heart. As such it makes communication alive and interesting (as long as it is conducted reasonably well).
