Troll whisperers aren't necessarily very good at hacking tools, so there's always an opportunity for geek synergy in helping them to automate their hand-crafted techniques, giving them a software force-multiplier for their good sense. For example, Teresa invented a technique called disemvowelling -- removing the vowels from some or all of a fiery message-board post. The advantage of this is that it leaves the words intact, but requires that you read them very slowly -- so slowly that it takes the sting out of them. And, as Teresa recently explained to me, disemvowelling part of a post lets the rest of the community know what kind of sentiment is and is not socially acceptable.
When Teresa started out disemvowelling, she removed the vowels from the offending messages by hand, a tedious and slow process. But shortly thereafter, Bryant Darrell wrote a Movable Type plugin to automate the process. This is a perfect example of human-geek synergy: hacking tools for civilian use based on the civilian's observed needs.
