Wikis and Happiness

Over at the Wikinomics, the Blog, Anthony Williams published this picture of the process comparing email collaboration versus wiki collaboration: Wiki collaboration leads to happiness.

One point of contention was whether the faces on the email said should be happy faces or frowning faces. Anthony goes on to say in Wiki collaboration leads to happiness:

"Are occupational spammers blissfully overflowing your email inbox with overweight word documents and seemingly ignorant of the rising tide of wiki enlightenment that is bestowing happiness on a growing legion of devout followers? Or, are emailers painfully self-aware of the tragic cycle of email misery that obscures their path to wiki salvation?"
