This chart highlights the global spread of Twitter. The U.S. is the most Twitter-ific (sorry, very corny) nation on the planet followed closely by Japan, Spain (Spain? Really?), and the U.K.

What makes Twitter such a hot application? It’s the next step in the democratization of the web. By leveraging the power of social communities everywhere, Twitter has grown in influence and authority.

Will it become the next YouTube or Facebook success story? Well, yeah, it kind of already is.

Will it be monetizable? That remains to be seen. YouTube, Facebook and MySpace continue to struggle with the monetization of their sites. That’s not to say they aren’t hugely successful, it’s just to say that they’re still in that early growth curve (just like Amazon was) where they haven’t started generating all of the profits they have the potential of generating.

There are two YouTube viral video campaigns we’ve blogged about recently. One is an Extended Stay Hotels campaign and the other is a Wii campaign.

Both used the same vehicle — YouTube — to get people talking about their products. But one of them succeeded and one of them failed miserably.

Which one succeeded? The Wii spot, which does a fabulous job of engaging the viewer in an uplifting, fun online experience. The net result, after watching the spot, is a positive one. Viewers complete the experience by saying, “Cool! That was awesome!”

(Okay, correction, viewers under the age of 21 say, “Cool! That was awesome!” The rest of us use different language, but you get our point.)

On the other hand, there’s the Extended Stay Hotels campaign which ends with a young lady licking the toilet at one of their hotels. We’re not kidding. She licks the toilet to show that the hotels are clean.

The spot was so offensive that it was recently pulled from YouTube by the hotel chain. We’re sure the Winston-Salem, N.C. office of Mullen, who, according to AdAge, created the campaign, tracked YouTube hits, and we’re sure they were huge, but if you get to the end of a YouTube commercial and say, “Ewwwwww!” instead of “Cool!” then you’ve done yourself a disservice.

How did Extended Stay allow this to happen? If we were to guess, there was a young, wippersnapper team of creatives who have won a bunch of awards for edgy, outrageous work. They probably mentioned their award-winning campaigns that “built awareness” for other clients just prior to presenting the storyboards to the Extended Stay marketing team.

And you know what? The truth is, there’s definitely a place for edgy, outrageous work. If you get it right, you can increase mindshare exponentially, which ultimately translates to sales. But that’s the trick — you have to get it right.

In the case of Extended Stay hotels, they got it wrong. In a big way

Here’s an insiders trick: If you’re a marketing director and you have a hip, young creative team presenting edgy, outrageous work, there’s a simple test to see if you should approve it.

At the end of the spot, if you say, “Ewwwwww!” then kill it. If you say, “Cool,” then have at it.

There’s a lot to be gained by doing work that breaks through the clutter. But doing work that’s groundbreaking is a little like investing in a start-up — there’s a pretty good chance you’re going to fail, but if you don’t fail, you just might hit a grand-slam home run.

Using the 60 Second Marketer “Ewwwww!” test is a simple, yet effective, way to tell if a groundbreaking spot has a chance to grow sales and revenue. Give it a try next time you’re facing a young team of wippersnapper creatives.
