Twitter seems to be buzzing about a new Nokia ad with Bruce Lee and ping pong. I’ve gotten several tweets about it, at least two with nothing but the prompt “This is the coolest video ever!”

Both times I received a tweet like that, I clicked on the link. Why? If Nokia sent me a direct email that said, “Here’s the coolest link in the world,” I would not have clicked. But random people in TweetLand? I listen to them.

That’s the power of word-of-mouth marketing. When you get a recommendation from a friend, even if it’s not a close friend, you’re more likely to take a look.

Here’s the video. I keep trying to figure out why everyone thinks it’s the bomb.
