Sounds to me like the real solution is to anonymize everything. 
No one knows who posted what or who liked what!
This has some clear benefits:
- No one gets influenced by big names
- Makes it more difficult to follow a certain clique or crowd
- No one can form a bias against someone because of something they said in the past
I'm sure there's more stuff too.
I think it would also be fun if reviews/pitches were un-anonymized after the thread was closed/locked. Go see your mortal enemies that you actually ended up agreeing with on certain points.
