A tasty use for Twitter

200 million people are on Twitter, but it's hardly a mass medium. It's a great way to send messages to your friends a few followers, very few marketers, however, have figured out how to use it to sell products to the general public.

Unless your hungry for Tacos in Texas.

In a creative combination of two relatively new technologies, Stripes Convenience Stores is reposting tweets onto digital billboards around lunch and dinner time, letting people share their love of tacos to a wider audience than just their followers.

While the design of the board isn't very good and the Tweets aren't incredibly creative, it's a nice way to bring the immediacy of social media to outdoor and have real people endorse the product at the most appropriate time.

Earth shattering? No. Smart? Definitely.
