Well, perhaps not quite that dramatic. But a public conversation/debate between James "Wisdom of Crowds" Surowiecki and Malcolm "The Tipping Point"/"Blink" Gladwell is still pretty interesting, at least for those of us interested in social networks, framing and memes, group behavior, and cultural change. Surowiecki and Gladwell are two of the best-known social observers around right now, and they both make trenchant observations apt to trigger cascading aha! moments for readers. Slate is hosting a week-long conversation between the two writers, now on day three. The conversation remains polite, but we're still hoping for a strike to the jugular at any moment.
