What if they are both right?
Facebook model is phenomenally successful, clearly Zuckerberg must be right.
4chan model is phenomenally successful, clearly Poole must be right.
The only issue I see here is our polarizing attitude and insistence that one must be better than the other.
It's not a zero sum game. We have both because they target different, non-overlapping scenarios and we have hundreds of other, smaller communities, each with different rules.
We don't discuss it when people who like bitter chocolate claim that those who like sweet chocolate are "totally wrong". I think we have enough space on our servers for both Facebook and 4chan.
