Mazda's campaign starts as a simple poll question on the homepage of LinkedIn. It asks: "Do you like your car?" The answer choices are just as simple: yes or no. Once the user clicks on an answer they are taken to a page where they can view results from people like them, meaning people with similar titles and in similar sized companies. Linked In of course has all of this information about because the user gave it to them when they registered.

Here's why this campaign works:
1. It's not about Mazda.
Mazda is simply the sponsor. At the same, time they do a nice job of inserting themselves into the user experience via light branding.
2. It's engaging yet commitment free.
Users answer one easy question, "Do you like your car?" There's no commitment to buy something or be bombarded with an advertisement for something they don't want. In fact, even if they answer "yes," and are not in the market for a new car now, ythey are still exposed to the Mazda brand.
3. It rewards the user with relevancy.
The data delivered back to the user is relevant to them, since it's based on their title, company size, etc. It's also interesting to look at -- one might argue more interesting than an ad. In fact, I'd be curious as to what the average exposure time is per experience.
By placing the user at the center and creating an experience around them, Mazda succeeds in advertising in a very Web 2.0 way.
