How do you deal with a Snarker? Everyone meets them, every office has one or two (if they are lucky) and even the bloggernacle has at least one.
The real question that a Snarker represents is how to deal with humorists. If you are Bill Clinton, how do you deal with Doonesbury?
You have several options. You can ignore a humorist. If everyone snubs them, they go away, though the world is often a grayer place without them. Not to mention, almost every community will generate its own humorist or two. In getting rid of one, you need to ask yourself what will take his or her (or their) place. If the Onion (or Sugar Beet) falls, what comes next?
You can fight with them. Shower them with attention and provocation. They will be grateful and you will encourage them to do whatever it was that got your attention to start a fight.
Or, you can try to encourage good humor and ignore the bad. Humorists generally broadcast for an audience. If what they do creates attention and comment, then they do more of whatever that was.
The maxim, of course, is that whatever you feed will grow. The approach to take to any humorist is to treat them like a bonsai, using all the tools available, to encourage the kind of humor that you want.
The rule works for a blogging community, a congregation or a classroom.
Good humor doesn't just occur on its own, it needs cultivation.
