] # Allow others to edit a posts tags. Won't this just
] stress the system as tag edit wars break out?
] # Allow others to add tags but give them less weight.
] Tricky to fine tune.
] # Combine with a reputation system that devalues people

Discussion on the means that the present folksonomies use to disrupt spamming, and where it could go. This isn't really a fear for the 'stream though. Complexity is already there.
