Hm. I'm feeling some of this at the moment. "... a lone dissenter is likely to fear voicing his or her opinion because with technology tools backlash can be magnified and distributed far more quickly. So even if there are some flaws in the post - a lone dissenter is unlikely to make that known for fear of instant backlash." I have been thinking today about the distinction between groups and networks. Groups require unity, networks require diversity. Groups require coherence, networks require autonomy. Groups require privacy or segregation, networks require openness. Groups require focus of voice, networks require interaction. The group I am with right now is very intent on being a group. That doesn't interest me. I have no wish to lose my identity and my freedom, my empowerment. Because a group is subject to this very objection - backlash, groupthink, the works. But a network is not.
