Need a unique advertising method--or money to fund one? Paying everyday people to ad-wrap their cars with a 3M-produced vinyl material that actually preserves car paint is growing in popularity according to this article in The New York Times . Advertising agencies like FreeCar Media in Los Angeles coordinate businesses with people that consistently drive routes that would give the car ads high visibility. Depending on who the deal is coordinated with, drivers of ad-wrapped cars can make as much as $800 a month. 

But the advertising method isn't always limited to big-budget companies, as Brian Morris, owner of a pool construction and repair business in Phoenix, knows; he has had 30 vehicles wrapped with ads for his business. 

What sorts of things do you do online? You probably e-mail, chat, shop, read news, share photos, do research, post reviews, conduct business and more--and all these elements make up your digital identity.  

I found a neat, graphical digital identity map by Fred Cavazza on  Conversation Agent that organizes the different ways we use the internet and how close they are to our real identity. 

Some aspects of your digital identity include:

• Details--how and where you can be contacted personally
• Publication--what you share via sites like Flickr, YouTube and Del.icio.us
• Opinion--your likes and dislikes, shown through reviews and sites like Digg and Stumble Upon
• Audience--who you know through social networking sites

What about your customers or target market? When you think of them, can you create a similar map of their online activities? It could help you better reach them and understand where they're coming from and where they're going.
