Xeni Jardin is one of the co-editors of Boing Boing.  She posted a piece on Edge.org called Online Communities Rot Without Daily Tending by Human Hands that essentially fleshes out the thinking behind her very descriptive title. (Hat tip to Ed Cone for pointing to it).  Among the very smart things she wrote I found this bit to be flat out brilliant:

Finally, this year, we resurrected comments on the blog, with the one thing that did feel natural. Human hands.      

We hired a community manager, and equipped our comments system with a secret weapon: the "disemvoweller." If someone’s misbehaving, she can remove all the vowels from their screed with one click. The dialogue stays, but the misanthrope looks ridiculous, and the emotional sting is neutralized.

Now, once again, the balance mostly works. I still believe that there is no fully automated system capable of managing the complexities of online human interaction — no software fix I know of. But I’d underestimated the power of dedicated  human attention.

I suspect Ed is hunting for a Typepad version of the disemvoweller as we speak.  If I got more than my normal quota of one comment per millennium I probably would.
