From Ebbie: Mind you, trolling is not necessarily injurious.

Very true. I like to think of myself as a "Joyful Troll," who deliberately posts provocative messages with the intent of getting a long lists of responses, or, occasionally, changing the direction of an ongoing discussion.

The difference between me and "Nasty Trolls," however, is that I aim to provoke outbursts of laughter.

Though I admit -- sometimes, my aim is off.
